Thanks for everyone who requested testing air filters and please let me know which brands you want tested in the next round. Also, here's the list of the ones I tested. Thanks again! Products Tested In This Video (in no particular order): EPAuto: amzn.to/3lbyw9E WIX: amzn.to/3aQloBN Fram: amzn.to/3j1stm0 AC Delco: amzn.to/3j2J5tv Purolator: amzn.to/2Qc3pwl K&N: amzn.to/3aJlTh8 K&N Cleaning Kit and Oil: amzn.to/2Qb3Kzk
We've legitimately used this man's videos to change what kind of tools and parts etc that we use on the generators we build at my work, his videos have actually solved some issues we've been dealing with and helped make our products better. Can't give any better praise than that
I just wanted to come back and say thanks for taking the time to do this. There are so many misinformed people and I was one of them before this. I share this video at least once every three months when discussions about air filters and cold air intakes comes up.
This guy has a gift. And he doesn't bother us with too much talking. He just gets to the point and tells you what you need to know. I've come to this channel a few times and I haven't wasted anytime with his videos. Very nice and informative. I am grateful!
If you notice when you install a filter, there is guides made from glue sometimes (guess it keeps the pleats together). Put that side towards the intake pipe I have put it the other way and ran less efficiently because of turbulence (more noticeable with bigger air box or pipes) but they are less restrictive.
I was an air filter engineer for many years a long time ago at one of the brands you tested. You do a great job, as always and I applaud your very logical and thoughtful approach. However, I'd like to make a few comments about this report. 1. Flour or powder do not make good test mediums. They tend to agglomerate, and in any case do not compare well with industry standard contaminants. 2. During testing, an even distribution of contamination introduction is critical. Thus, semi-random placement of the test medium can drastically affect the test outcome. A typical test set-up involves an aspirated cloud of contaminant for more consistent and even dispersal to assure a more realistic particle size distribution. 3. Industry standard contaminant particle size is inversely proportional to particle count. In fact, the number of particles increases dramatically (exponentially) as size goes down. 4. Engine wear potential is attributable to particle make-up, i.e. Is it silica or organics, etc., and quantity. Thus, engine wear risk drops dramatically with particle size. Internally moving engine parts, especially rings & valves, are not usually affected by very small particles in small quantities. Five microns is about 1/100000 inches. Concern for wear begins around 10,000 microns or below .005". 5. Flow is generally concentrated in any filter, despite shape and flow diverting techniques used. Placement of contaminant on the filter media by hand is less realistic. 6. Contamination which agglomerates will increase pressure drop and increase contamination removal efficiency giving erroneous results. As a function of actual wear potential, the K&N, though inefficient according to your test, may actually be the best protector because of its affinity for the larger silica particles seen in real life. Still, your test report is very persuasive! Thank you for reading!
Smear some petroleum jelly on the clean side of your air cleaner, run a paper filter for a week, see how much it lets through, then do the same with a K&N...the petroleum jelly will be full of gritty crap...I will never use a K&N filter again.
@@mebe2k I would say your petroleum jelly test is brilliant! We used a Coulter Counter wafer downstream of the filter to catch what passed through and this was very effective, especially in measuring particle size distribution. The really small stuff was impossible to filter without serious pressure/flow loss. But, K&N elements were never tested, way back then. Great suggestion you made!
@@baconmunchers629 My best recollection is Fram and Purelator were always top performers but I really have no idea how they compare today. When you take the physics into consideration of what is happening, it is generally true a greater pressure drop is indicative of contamination buildup, thus further suggesting your engine is being protected. Also, the number of pleats in the filter media reduces pressure drop from the outset by lowering the cfm of air per square inch, assuming no major differences in the media itself. I would elect to use the filter with the most pleats (most media) and significant pressure drop with increasing contamination. I don't believe the engine's output is noticeably compromised with one inch of water pressure increase and, in any case, I'd rather know I was protected. Cars can run without oil filters for years, as long as the oil is changed regularly. But, contamination entering the engine through a poor filter directly affects the combustion area! Air filtering is much more important than oil filtering!
By far, the best UA-cam channel I've ever seen. As a head of household, father and handyman, your videos have benefited me the most and helps me to make better decisions with the products I buy. Can't thank you enough for that!
This by far has been the best channel I've ever found. I remember when it was all seafoam and epoxy and a couple thousand subs. You sir deserve an award for all your hard work and dedication. Best content from any testing channel.
I’ve used OEM or Wix for years in a variety of vehicles, so I am very glad the Wix did well. Really appreciate the passion and thoroughness you put into your videos. Looking forward to what’s next, take care!
That's a low standard tho. I'm pretty sure that he isn't guilty of treason and wants steal from us while trampling on the constitution like today's politicians, from both left AND right.
Particle counter! Dude!! When I first started watching you ..you were like: Lets see how long this lawn mower engine runs on human pee! You are now outdoing Consumer Reports! God, I hope you are getting paid for this. Obviously...awesome job as usual!
@@amsb4dafunk406 he gets paid whether you press skip ad or not, just like he gets paid even though I have premium and don't see any ads, but he still gets revenue off the view.
Airflow vs filtration , which do you want ? There's going to be a trade-off either way. About the only way to "gain" a little bit in both departments is to increase the size of the filter. Like an old v8, stack as many round air filter elements as you can. You'll maintain decent airflow with decent filtration for a longer period.
I've always had a suspicion he has an oil filter test in the works. But I cant be sure of course. You have to imagine running multiple brands of oil filters through the same vehicle for 3500 miles minimum takes time.
I’m at 15,000 mile oil change intervals on my Toyota Corolla and I’ve had a oiled K@N filter for over 100,000 of those miles. I have seen nothing atrocious in all the oil samples that I have sent off so I would not worry too much.
@Green Monkey that's not really a good metric considering ingested air never comes in contact with motor oil. Biggest place you'll see the difference is in the intake track. Fine grit wearing on valve seats and guides. In other words, that yota will last maybe 200k? Where others might last 4-500k
I used to hang out on the TJ Wrangler forums often and the more experienced guys there would always talk trash about K&N filters being overpriced and not working well. That was before this video was uploaded. Looks like they were right.
I work at an auto parts store and I usually recommend customers buying WIX, over any of the other filters, watching this makes me feel better about my recommendations that I give out.
@@ronb6182 It’s not about having a customer pay more money the most expensive filter is a K & N depending on the car make it usually is about 50 bucks, Well mycrogard is the cheapest it doesn’t last long, for five bucks difference on a wix and for better quality you can’t go wrong.
K&N are referred to rock catchers on a well known oil website, so I'm not surprised. Not surprised to know that Wix came out on top, but would have thought Fram would have done better. Their orange cans are low end, but the Ultra is a contender with some of the highest rated filters out there.
This channel is killing me. Like this dude does the most thorough testing on youtube imo well him and gamer nexus if you're into computers. He has the tools for freaking everything and the few things he doesn't have he creates himself. Then his scientific method is damn near flawless. I'm like this guy needs a lab coat and some googles at least that's what I keep expecting.
Certainly would be nice to see a ‘verified by recognised consumer tester’ or something a kin to it. It’s how Thatcham in UK 🇬🇧 stated out, a group of car enthusiasts with their own money bought a bunch of steering locks and tested them for legitimacy against claims, they moved onto car alarms, immobilisers and then really took off. google Thatcham or check out the link ua-cam.com/users/ThatchamMIRRC001
Thank you. I have been saying it for decades that K&N is great for flow but terrible on filtration. I have seen many diesels with K&Ns come in with dusted turbo wheels (saw blading) with no obvious pre turbo air leaks. I avoid them on all my vehicles.
@@vikasshelke5544because you don’t want to risk your engine ingesting sand, rocks, leaves, potato chip bags, etc. You want a filter to prevent that but you want one with low restriction. Ideally a racetrack won’t be super dusty so fine filtration isn’t really needed.
As the comments have shown, you've helped out so many people out by doing these tests. i hope you've never doubted yourself. thank you for saving me a lot of time, worry, frustration and hard earned money. You're a hero in my book. You and ChrisFix are definitely the most important Auto-Based UA-camrs. So many of us rely on your experience. You're doing an amazing job.
Paul Stan same that’s hilarious. Already started shopping purolator so I can get the k&n out. Also Toyota oem blades on my wife’s Highlander are the best.... just took my rain-x off. You’re welcome
I formerly worked for an automotive parts manufacturer that was represented in this testing. I find PF's testing approach to be VERY credible and findings very interesting. One thing to note, any engine air filter is actually MORE effective at filtering particulate with a bit of age/usage as the previously captured foreign material in the filter media increases the filter's own filtering capacity. That made sense to me during product training years ago, but would have never occurred to me beforehand. There's definitely an argument for NOT changing this filter prematurely as some of us enthusiasts are prone to do with "over maintaining" our vehicles. Just wanted to add this interesting factoid. Nice job PF, love your content!
I guess that’s why Subaru recommends you change the engine air filter every 30,000 miles on the Ascents. I was about to change I at every oil change before I noticed the manufacturers instructions.
Not to take money out of P/F's pocket but, look up "oil filter test" by CarsNToys… He has a few shockingly thorough and very entertaining oil filter tests.
I'd like to see a base "model" air filters vs the premium line air filter of the companies, particularly STP vs STP Premium(which I use STP premium). Are the "better models" actually any better than their basic filter. You could use what brands autozone/o'Reillys carry.
Catch is... Does the manufacturer making house brand filters today also make those same filters 6 months from now? Some chain stores insist that their cheap house brand filters are Wix because they sell Wix as their top line. When in reality they're house filters are made by Champion. Etc.
his previous tests from using basic to premium have almost always been better the higher up it is but it would be interesting to see by how much different it is
Why? They would allow about the same amount of contaminants through them as the K&N. Most are derivatives of the K&N. Why buy junk? Little gains in horsepower is no reason to trash an engine.
Working Guy I would be interested to see if some of the non oiled versions would be any better. I’m sure the increased air flow they advertise comes at a cost of filtering efficiency. I would be curious to see as how much more debris they allow through vs oiled filter.
Some companies like S&B make a supposedly high performance paper filter that you can get instead of the oiled alternative too, I’d love to see one in the test
Once again I'm impressed with the high quality comparison and easy to decipher results that you deliver. Thank you for offering the best and most dependable comparisons available on the internet today.
Great job as usual! Your results echo what most of us already know. The "secret" to K&N's great breathing capability is its extremely poor filtration performance.
I won't pretend that oiled filters are great at filtration. However, I had just used one in my V8 pickup for around 50,000 miles with no cleaning and no issues. Mostly road driving without much dust, but not always. Some offroading, but not much. As far as I can tell, it ran the same or better until I totalled it a month ago. It was 21 years old, and very reliable. I mean no malice; I'm just wondering what your thoughts are about this. I'm beginning to think fine filtration isn't as important and coarse filtration.
A few years ago, a friend with a 3/4ton diesel changed over to K&N from OEM. He had had oil analysis done several times prior to changing over, so he had a baseline for comparison. After installing the K&N the next oil analysis flagged "silica contamination" (dirt), and they suggested a leak in the air intake system (check hoses, clamps, etc.). No leaks or loose clamps were found. So he removed the K&N and reinstalled the OEM. The next analysis showed a reduced, but still high, silica contamination, he kept the OEM system in place. With each oil change and each analysis, the silica content went down. It took 4 or 5 oil changes to get back to the baseline he had before he installed the K&N.
@@michaelcohen9363 It is impossible to get 100% of the oil & contaminants out in one oil change. As I said it took 4 or 5 changes to get it back to normal. I'm pretty sure he used Blackstone Labs. Indications of contamination go up a lot faster than they come down.
This explains much. When I crashed my Suburban through a bakery with my K&N filter, performance was notably worse. However I was able to make biscuits from the exhaust.
wisenber I was using K&N air filters when Mt Saint Helen’s erupted and ash was blowing thru the air everywhere! I knew a lot of people that weren’t able to keep their vehicles running with all the ash clogging up their filters. But my K&N never gave me one bit of problems keeping the ash out of my engine nor ever clogged either! Same goes for all my ATV’s and dirt bikes using K&N air filters in the sand or dirt/mud. Never once have I gotten any sand or dirt in my carbs or engine. But ridding in heavy blowing sand and dirt you do have to clean your filters more often!
Another cool project might be to test the integrity of wiper fluids at really cold temperatures. Right now the weather in my area is about -4°F and I have wiper fluid that’s supposedly good to -25 and that is not the case. I think a test like that would be cool with some name brands and some generic ones.
I'm a filtration test engineer for a living and, I have to say, nice job for a DIY style setup. We use pretty stringent guidelines on contamination and particle testing, but your setup was a good idea for a general idea of how the filters perform. The only thing I'd recommend on this one is to think about the fact that a lot of filters are designed for the rated flow-rate of the engine inside the O.E. air box. Air dynamics across a plate mounted filter can do funny things to the measured restriction and cause it to spike or fall compared to when it's installed in a vehicle. You might be surprised how different the pressure loss can be in those situations. Other than that, nice job.
How would you say the idea of dumping contaminant directly onto the media works? Not sure that gives a real-world, or even valid hypothetical standard for testing...
@shankle farm respectfully, disagree. it's like when mythbusters shot frozen chickens out of an air canon to see if it would destroy a cessna.... Now in their example they found that both the frozen and thawed chicken did equal damage. But then they realized they were not using airplane grade windshield glass.... You have to test the practical application.
@@radiomantodd To be honest, the direct contaminant injection method has never been my favorite, but it can provide consistent results. However, this is only when using a proven contaminant standard. The capacities that are achieved in a lab are typically less than what you would see in the field. Dirt loading over a longer period allows for pathways to develop in the media and prolong the life of the filter.
@shankle farm Your point is half on target. They were all treated the same, which is good methodology, but it doesn't mean they will react the same on a flat plate compared to the OE air box. The airflow dynamics are completely different between the two and though one filter may stink on the flat plate it may excel in the OE air box and vice versa. As for the flow rate, it makes a big difference on how air is directed into and through the filter media. If the flow rate is too low it can actually cause turbulence around the pleats. If designed properly, the filter can act as a sort of air straightener and actually help with MAF noise.
This man is nothing short of Awesome! I have been watching him for years and I wish some big corporation would see his value and hire him to test products!
I'd like to see that too! Always been told Bosche oil filters were very good. It will be good to see an actual test of filters to see which oil filters are the best! Good to keep cars going for a long time!
@@sterrshow5016 nope. Some oem manufacturers actually just use rebadged other brands that are "cheap" quality and charge a dollar more than the same filter. Not only that but purulator and wix oil filters are top tier, bosche is fairly good for the price.
I feel like whenever walmart's supertech brand is available to compete it should. A lot of people look to use their stuff because of cost so knowing if they're junk or not would be useful
This has become my go to channel for testing consumer products. No one does testing like Project Farm! His results always surprise me. The air filter test got me again. I sure didn't think Fram would be outperformed! Thank you!
I once ran my own K&N versus Donaldson test in real-time. I have a Dixie Chopper XT2800 with a 28 HP Kohler EFI engine. It uses a heavy-duty canister filter. There are actually 2 filters in the canister. An outer filter PN P281575 and an inner safety filter PN P822858. The purpose of the inner filter is to keep any loose dust and debris from getting into the intake manifold when you're checking and/or changing the main outer filter. I have quite a few hours on this mower, almost 3,000, so I've had plenty of chances to change the air filter. Normally with the Donaldson filter, you wouldn't have to change the inner safety filter because it still looked like it was brand new. I tried the K&N E4961Donaldson replacement filter. I usually check the air filter at my 100-hour oil changes. I opened the canister up and pulled out the K&N filter and it still looked good. Then I looked in at the inner safety filter and it was filthy. That told me everything that I needed to know about the filtering capabilities of K&N filters. I threw both the inner safety filter and the K&N filter into the trash. I'm using nothing but the factory filters from here on out.
False. Dirty filters have increased particle capture efficiency because the small pores of the filter become plugged. The trade-off is reduced flow and increased resistance.
@You Wish Depends on what you consider best, better air flow? Or better filtration? I'll take better filtration any day and yes a filter does its best filtering when it is a little dirty.
Would be interesting to see results with an old-timey "Oil Bath" type air filter, where the air has to do a 180° turn in front of a bath of oil before going into the engine. I've been told by more than one mechanic, that those were 'the best'.
@@karlelliott9254 I have '72 Dodge PowerWagon that was originally equipped with an oil-bath type engine air filter. I swapped it out for a cartridge type a few years back, and am wondering if I made a mistake doing so.
The trick will be finding an oil bath filter of sufficient airflow capability so it's a fairly even apples to apples comparison for pressure drop and flow rate. Probably have to find an older junk yard engine in a hopefully common engine displacement so the air flow numbers more or less match. (like an old 350 with an air bath vs one with a round and one with a square filter.)
Karl Elliott my uncle used Allis Chalmers for years they were the best tractors money could buy on time,,, The last brand new one he bought was an AC 7060 darn good tractor however those Fords were pretty good also.
My 68 JD 4020 still runs fine and the sand separator has come apart so the oil bath is taking in everything and the plugs will look new no matter how long they're in it. The 55 Chevy pickup was oil bath and it never used more oil than it did when it was bought used which was very little.
@@ProjectFarm Does the Toyota genuine carbon cabin air filter do a better job (at 10 x the cost) then the carbon air filter I can buy online? Does the Toyota genuine non-carbon fiber cabin air filter do a better job (at 5 x the cost) than the fiber cabin air filter I can buy online? I find that the genuine Toyota carbon cabin air filter comes with that new car leather smell embedded in it, but after a while it absorbs all the bad smells, particularly in damp weather with the cabin air on recycle in the city, so it ends up smelling pretty bad if you put the heater or air-conditioning on. Great at first, but needs changing after about 12,000 miles to get rid of the smell, even if it isn't clogged. The fiber filter has no embedded smell, and tends to absorb less smell.
Great idea especially for allergy prone people like myself. I found that many companies manufacture them but the fit into the filter bracket was terrible.

That I'd like to see and also do tiny carbon activated filters for cabin filtration actually outperform non activated carbon filters?
Have used Wix for years, but used to use Fram. Went over to Wix due to advice by knowledgeable mechanics and was told Fram was trash. Good to have confirmation in real world tests that I had received good advice. Nice video!
Wix is no longer Wix though. It got grabbed up by another filter company --- boo hoo. I also believe that the NAPA Gold line was Wix -- and if the conglomeration of them is true, then the NAPA gold is now suspect.
Seeing a lot of support posts and only ~1,800 patreon patrons. This is THE most informative, results driven, unbiased, genuine channel on this platform. Support this man if you can!
@@ProjectFarm I think your testing method for particle pass through may have been flawed. K&N is unique in that it uses oil to catch particles. If you apply several years of particles (aka dump flower on it) all at once without cleaning and reoiling the oil becomes saturated and ceases to function.
Project Farm’s testing is unlike any channel I’ve watched! I’d like to add two things: 1) K&N filters filter particles better when sprayed with the K&N oil, however it is a maintenance item, and I’ve had these run dry and ruin a Mass Air Flow Sensor before. However, they work great in the dust with oil applied. 2) Video Idea: Comparing resistance to flow through different spark plug wires, I. E. OEM, Performance wires, versus store bought/common brands.
I've actually heard that the oil on a K&N can be drawn out as fine droplets, and clog up the wires on MAF sensor. How true that is, I don't know....I have used K&N filters for over 15 years now without any issues.
The MAF may get dirty, true, but I've never had a dirty MAP sensor (in my experiences with Hondas). In my most recent oil analysis from Black Stone on my EM2, there were 0 (zero) insolubles in my oil, and average was 1; I've got a K&N drop-in air filter.
This is a great idea. I would love to see how the cheaper supertech filters compare to the fram and wix filters. I have heard that besides the top tier ultra synthetic filter, fram filters are crap. Wix has been known to be good overall, but i want to see what you are paying for.
I really appreciate your hard work and attention to detail. I would also enjoy seeing an oil filter test around the same test parameters. If you decide to do an oil filter test, can you do one based on either the ls/lq style Chevrolet engine like in your suburban or even better one based on filters for a Cummins engine? Or even better, maybe both. I'm curious to see if there are any notable filtration differences between gas burner and diesel.thank you again for all your hard work and time. I can only imagine the r and d put into some of your test fixtures. Your efforts are much appreciated.
Again you have done a great service to the general public, I dont know why you dont have a TV show on Saturday mornings! Yes I do, You are fair and unbiased! Thank you so much for what you do. I am sure there are times you ask yourself if all the money and time is worth it. All I can say is Absolutely! And we appreciate all your efforts, Thanks gain.
Fram is capable of making a good filter. Their orange ones (PH part numbers) are garbage. Their higher tiers are much better, but the build quality and filtering performance of their cheapies always gives me pause.
Stupendous! This is information unavailable anywhere else, and it's VERY useful. Man oh man you really do an amazing job here, and it's HUGELY appreciated!
The biggest problem I've seen with oiled air filters is oil coating of the mass air flow sensor element on MAF equipped engines. It's a gradual process (and usually accelerated by someone over oiling the filter after cleaning), but can result in a fine coating of oil and dust on the sensor element. For hot wire sensors this insulates the sensor which can result in an artificially low airflow reading creating a lean and overadvanced condition. Nothing a $10 can of MAF cleaner spray won't fix, but it pays to be aware of it. Speed density cars (or non-hotwire MAFs) need not worry.
I buy a house brand maf cleaner for 3$ and for an average time of one minute to pull the sensor and blast it clean it's good cheap preventative maintenance.
Same with turbocharged or supercharged vehicles. Run enough boost and you’re liable to oil up a wheel or screw. Which then could allow particulates to cling on and score up a compressor
Church Automotive Testing Dyno Tuning 99% of the time the reason people have problems with their oiled filters is cause their over oiling their filters. I have a 95 Dodge Ram with a turbo charger and a 2018,Kia Soul with a turbo charger among many other vehicles previously with K&N air filters and have yet to ever have a problem myself. But the ones I’ve helped that has had problems have always sprayed way too much oil on their filters. K&N air filters are only supposed to have a light layer sprayed on the filter. If your sucking oil on to other parts in the engine then it’s most likely been oiled too much!
@@ProjectFarm You are the only UA-camr i trust when it comes to producttesting. I would bet money that you wouldnt trick us! Also i love the the unbiased conclusions. Btw.

ALSO can you please make a rating home many times which brand won in the testings??
Wow thank you so much, this test has changed my perspective on k and n filters. I have these filters in all of my vehicles, that will now change. God bless and be safe
I would like to see you do a similar test on auto oil filters. I searched your channel and did not see a video like this. This air filter video was great info!!
@@ProjectFarm Oil filters are another beast that comes in different forms. Amsoil makes a full flow filter that's very good but when used with a secondary fine filter is unbeatable. Bypass oil filters can't be beaten. Some big dirt equipment comes with full flow and bypass filters.
Very fascinating the "contraptions" that you come up with to perform your "experiments". Also, the various instruments that you have bought or made to perform these tests is incredible. Thank you for making and sharing this video.

I just wanted to come back and say thanks for taking the time to do this. There are so many misinformed people and I was one of them before this. I share this video at least once every three months when discussions about air filters and cold air intakes comes up.
Thanks so much!
I have a front ram true cold air intake with a k&n filter on my 1uz.. fight me!

Maybe my gift is to appreciate others and encourage them in their tasks toward greatness. Huzzah. I found something that I'm good at!
If you notice when you install a filter, there is guides made from glue sometimes (guess it keeps the pleats together). Put that side towards the intake pipe
I have put it the other way and ran less efficiently because of turbulence (more noticeable with bigger air box or pipes) but they are less restrictive.

Engine wear potential is attributable to particle make-up, i.e. Is it silica or organics, etc., and quantity. Thus, engine wear risk drops dramatically with particle size. Internally moving engine parts, especially rings & valves, are not usually affected by very small particles in small quantities. Five microns is about 1/100000 inches. Concern for wear begins around 10,000 microns or below .005". 5. Flow is generally concentrated in any filter, despite shape and flow diverting techniques used. Placement of contaminant on the filter media by hand is less realistic. 6. Contamination which agglomerates will increase pressure drop and increase contamination removal efficiency giving erroneous results. As a function of actual wear potential, the K&N, though inefficient according to your test, may actually be the best protector because of its affinity for the larger silica particles seen in real life. Still, your test report is very persuasive! Thank you for reading!
Thanks for the feedback.
Smear some petroleum jelly on the clean side of your air cleaner, run a paper filter for a week, see how much it lets through, then do the same with a K&N...the petroleum jelly will be full of gritty crap...I will never use a K&N filter again.
@@mebe2k I would say your petroleum jelly test is brilliant! We used a Coulter Counter wafer downstream of the filter to catch what passed through and this was very effective, especially in measuring particle size distribution. The really small stuff was impossible to filter without serious pressure/flow loss. But, K&N elements were never tested, way back then. Great suggestion you made!
Hey Chip D - What brand would you buy for your own vehicle?
@@baconmunchers629 My best recollection is Fram and Purelator were always top performers but I really have no idea how they compare today. When you take the physics into consideration of what is happening, it is generally true a greater pressure drop is indicative of contamination buildup, thus further suggesting your engine is being protected. Also, the number of pleats in the filter media reduces pressure drop from the outset by lowering the cfm of air per square inch, assuming no major differences in the media itself. I would elect to use the filter with the most pleats (most media) and significant pressure drop with increasing contamination. I don't believe the engine's output is noticeably compromised with one inch of water pressure increase and, in any case, I'd rather know I was protected. Cars can run without oil filters for years, as long as the oil is changed regularly. But, contamination entering the engine through a poor filter directly affects the combustion area! Air filtering is much more important than oil filtering!
I really appreciate that I can come back and watch years later as a reference. Blessings
Thanks!

Great suggestion! Thank you
@You Wish Thanks for the clarification
Airflow vs filtration , which do you want ?
There's going to be a trade-off either way.
About the only way to "gain" a little bit in both departments is to increase the size of the filter.
Like an old v8, stack as many round air filter elements as you can.
You'll maintain decent airflow with decent filtration for a longer period.
@@MrTheHillfolk To an extent. But, as some other tests have shown, design and material differences can be an improvement on both, compared to stock.
I've always had a suspicion he has an oil filter test in the works. But I cant be sure of course. You have to imagine running multiple brands of oil filters through the same vehicle for 3500 miles minimum takes time.
This channel is honestly the most useful and fundamental source for everyday applications.
Thanks so much!
So glad I watched this. Used to swear by K&N, had no idea the potential damage it was causing.
Thanks for watching!
I’m at 15,000 mile oil change intervals on my Toyota Corolla and I’ve had a oiled K@N filter for over 100,000 of those miles. I have seen nothing atrocious in all the oil samples that I have sent off so I would not worry too much.
@Green Monkey that's not really a good metric considering ingested air never comes in contact with motor oil. Biggest place you'll see the difference is in the intake track. Fine grit wearing on valve seats and guides. In other words, that yota will last maybe 200k? Where others might last 4-500k
Well ya it is pretty much free air flow to get more power.
I used to hang out on the TJ Wrangler forums often and the more experienced guys there would always talk trash about K&N filters being overpriced and not working well. That was before this video was uploaded. Looks like they were right.
I sell parts and recommend products based off your results with a recommendation that customers watch your videos. Thank you for what you do Sir.
Thanks for sharing!
Sure is nice to have a friend who’s an energetic, resourceful, imaginative genius
Thanks!
I work at an auto parts store and I usually recommend customers buying WIX, over any of the other filters, watching this makes me feel better about my recommendations that I give out.
Thanks for sharing.
@@ronb6182 It’s not about having a customer pay more money the most expensive filter is a K & N depending on the car make it usually is about 50 bucks, Well mycrogard is the cheapest it doesn’t last long, for five bucks difference on a wix and for better quality you can’t go wrong.
😂
K&N are referred to rock catchers on a well known oil website, so I'm not surprised. Not surprised to know that Wix came out on top, but would have thought Fram would have done better. Their orange cans are low end, but the Ultra is a contender with some of the highest rated filters out there.
“Sizing up” is generally speaking not a good idea. There’s more that goes into a filter being “the right one” than the thread and the gasket.
2 years ago I watched this but watching again because I need to replace the filter on my truck. So glad this channel is here

Thank you. I have been saying it for decades that K&N is great for flow but terrible on filtration. I have seen many diesels with K&Ns come in with dusted turbo wheels (saw blading) with no obvious pre turbo air leaks. I avoid them on all my vehicles.
You are welcome! Thanks for the feedback.
Good for airflow but bad for dust filtration , why even put filter when you can let entire gush of air in for best of performance .
@@vikasshelke5544because you don’t want to risk your engine ingesting sand, rocks, leaves, potato chip bags, etc.
You want a filter to prevent that but you want one with low restriction. Ideally a racetrack won’t be super dusty so fine filtration isn’t really needed.
Lol K&N filters are good at nothing.
If someone has a diesel pickup for sale and states its had a K&N filter all its life I would RUN!

At least he already has a Gold Play button! Time to get that Diamond!
I formerly worked for an automotive parts manufacturer that was represented in this testing. I find PF's testing approach to be VERY credible and findings very interesting. One thing to note, any engine air filter is actually MORE effective at filtering particulate with a bit of age/usage as the previously captured foreign material in the filter media increases the filter's own filtering capacity. That made sense to me during product training years ago, but would have never occurred to me beforehand. There's definitely an argument for NOT changing this filter prematurely as some of us enthusiasts are prone to do with "over maintaining" our vehicles. Just wanted to add this interesting factoid. Nice job PF, love your content!
Thanks and you are welcome! Thanks for sharing.
I build just for fun an air cleaner for home uses and i used an car air filter. Do they reduce also pollen in the air?
I guess that’s why Subaru recommends you change the engine air filter every 30,000 miles on the Ascents. I was about to change I at every oil change before I noticed the manufacturers instructions.
The filtration gets better as the filter gets saturated, but it also gets harder for the air to pass through.
same thing for pool filters, in fact they had a special dust you dump into the filter that coats it so it filters better
I second the oil filter test, we need to know!
Great suggestion! Thank you
Amsoil is rated the number ONE oil filter.
It's rated at 98.7% at 20 microns.
All ratings are presumed false until tried by project farm in his garage by a group of his lawnmowers
Not to take money out of P/F's pocket but, look up "oil filter test" by CarsNToys… He has a few shockingly thorough and very entertaining oil filter tests.
I agree that this test should occur
Not only would it be good to see what oil filter is best, but also what oil filters actually do
This guy is the youtube standard. I love this channel!
Thanks!
I'd like to see a base "model" air filters vs the premium line air filter of the companies, particularly STP vs STP Premium(which I use STP premium). Are the "better models" actually any better than their basic filter. You could use what brands autozone/o'Reillys carry.
Thanks for the video idea.
Catch is...
Does the manufacturer making house brand filters today also make those same filters 6 months from now?
Some chain stores insist that their cheap house brand filters are Wix because they sell Wix as their top line.
When in reality they're house filters are made by Champion.
Etc.
Napa gold vs Napa silver. I got Napa gold in my car.
his previous tests from using basic to premium have almost always been better the higher up it is but it would be interesting to see by how much different it is
Knecht, Mahle and Mann air filters would be great too, to see how good they are.
Would love to see an air filter test of “Performance” air filters like AEM, Air RAID, Spectra,etc. Love the channel, keep up the good work!
Same!
Why? They would allow about the same amount of contaminants through them as the K&N. Most are derivatives of the K&N. Why buy junk? Little gains in horsepower is no reason to trash an engine.
Working Guy I would be interested to see if some of the non oiled versions would be any better. I’m sure the increased air flow they advertise comes at a cost of filtering efficiency. I would be curious to see as how much more debris they allow through vs oiled filter.
Some companies like S&B make a supposedly high performance paper filter that you can get instead of the oiled alternative too, I’d love to see one in the test
Great suggestion!
I always bought Fram, now changed to Wix. Thank you
Thanks for sharing.
And if the store is sold out of wix, you can get a Napa gold. Napa gold is made by wix

Great job as usual! Your results echo what most of us already know. The "secret" to K&N's great breathing capability is its extremely poor filtration performance.
Well, said!
I won't pretend that oiled filters are great at filtration. However, I had just used one in my V8 pickup for around 50,000 miles with no cleaning and no issues. Mostly road driving without much dust, but not always. Some offroading, but not much. As far as I can tell, it ran the same or better until I totalled it a month ago. It was 21 years old, and very reliable. I mean no malice; I'm just wondering what your thoughts are about this. I'm beginning to think fine filtration isn't as important and coarse filtration.
@@Mannyjv The logic is undeniable. You can flow air or trap particles you can't do both
This is so true lol
@@rtflone you can get a little of both. K&N must be enough filtration for all my vehicles.
A few years ago, a friend with a 3/4ton diesel changed over to K&N from OEM. He had had oil analysis done several times prior to changing over, so he had a baseline for comparison. After installing the K&N the next oil analysis flagged "silica contamination" (dirt), and they suggested a leak in the air intake system (check hoses, clamps, etc.). No leaks or loose clamps were found. So he removed the K&N and reinstalled the OEM. The next analysis showed a reduced, but still high, silica contamination, he kept the OEM system in place. With each oil change and each analysis, the silica content went down. It took 4 or 5 oil changes to get back to the baseline he had before he installed the K&N.
Thanks for sharing.
that doesn't make any sense, since all the silica content would be removed with the oil change...
@@michaelcohen9363 It is impossible to get 100% of the oil & contaminants out in one oil change. As I said it took 4 or 5 changes to get it back to normal. I'm pretty sure he used Blackstone Labs. Indications of contamination go up a lot faster than they come down.
@@glenatgoogle4393 "showed a reduced, but still high, silica contamination"
That wouldn't happen after the first one or two oil changes.

This explains much. When I crashed my Suburban through a bakery with my K&N filter, performance was notably worse. However I was able to make biscuits from the exhaust.
lol Thanks for watching.
wisenber I was using K&N air filters when Mt Saint Helen’s erupted and ash was blowing thru the air everywhere! I knew a lot of people that weren’t able to keep their vehicles running with all the ash clogging up their filters. But my K&N never gave me one bit of problems keeping the ash out of my engine nor ever clogged either! Same goes for all my ATV’s and dirt bikes using K&N air filters in the sand or dirt/mud. Never once have I gotten any sand or dirt in my carbs or engine. But ridding in heavy blowing sand and dirt you do have to clean your filters more often!
@@galejenness7615 I've been using K&N in my Suburbans for over 20 years. No complaints.

Another cool project might be to test the integrity of wiper fluids at really cold temperatures. Right now the weather in my area is about -4°F and I have wiper fluid that’s supposedly good to -25 and that is not the case. I think a test like that would be cool with some name brands and some generic ones.
Thanks for the suggestion.
-60F is available in Canada
I'm a filtration test engineer for a living and, I have to say, nice job for a DIY style setup. We use pretty stringent guidelines on contamination and particle testing, but your setup was a good idea for a general idea of how the filters perform.
The only thing I'd recommend on this one is to think about the fact that a lot of filters are designed for the rated flow-rate of the engine inside the O.E. air box. Air dynamics across a plate mounted filter can do funny things to the measured restriction and cause it to spike or fall compared to when it's installed in a vehicle. You might be surprised how different the pressure loss can be in those situations.
Other than that, nice job.
How would you say the idea of dumping contaminant directly onto the media works? Not sure that gives a real-world, or even valid hypothetical standard for testing...
@shankle farm respectfully, disagree. it's like when mythbusters shot frozen chickens out of an air canon to see if it would destroy a cessna.... Now in their example they found that both the frozen and thawed chicken did equal damage. But then they realized they were not using airplane grade windshield glass....
You have to test the practical application.
Thanks for the feedback.
@@radiomantodd To be honest, the direct contaminant injection method has never been my favorite, but it can provide consistent results. However, this is only when using a proven contaminant standard.
The capacities that are achieved in a lab are typically less than what you would see in the field. Dirt loading over a longer period allows for pathways to develop in the media and prolong the life of the filter.
@shankle farm Your point is half on target. They were all treated the same, which is good methodology, but it doesn't mean they will react the same on a flat plate compared to the OE air box. The airflow dynamics are completely different between the two and though one filter may stink on the flat plate it may excel in the OE air box and vice versa.
As for the flow rate, it makes a big difference on how air is directed into and through the filter media. If the flow rate is too low it can actually cause turbulence around the pleats. If designed properly, the filter can act as a sort of air straightener and actually help with MAF noise.
I swear before I buy anything important, I check if you reviewed it first. You good a great job! Keep it up

I once ran my own K&N versus Donaldson test in real-time. I have a Dixie Chopper XT2800 with a 28 HP Kohler EFI engine. It uses a heavy-duty canister filter. There are actually 2 filters in the canister. An outer filter PN P281575 and an inner safety filter PN P822858. The purpose of the inner filter is to keep any loose dust and debris from getting into the intake manifold when you're checking and/or changing the main outer filter. I have quite a few hours on this mower, almost 3,000, so I've had plenty of chances to change the air filter. Normally with the Donaldson filter, you wouldn't have to change the inner safety filter because it still looked like it was brand new. I tried the K&N E4961Donaldson replacement filter. I usually check the air filter at my 100-hour oil changes. I opened the canister up and pulled out the K&N filter and it still looked good. Then I looked in at the inner safety filter and it was filthy. That told me everything that I needed to know about the filtering capabilities of K&N filters. I threw both the inner safety filter and the K&N filter into the trash. I'm using nothing but the factory filters from here on out.
Thanks for the feedback.
The best filters are the ones that are changed on or before their scheduled interval .
amen!
Dirty one cleans better than a clean one
Thank you
False. Dirty filters have increased particle capture efficiency because the small pores of the filter become plugged. The trade-off is reduced flow and increased resistance.
@You Wish
Depends on what you consider best, better air flow? Or better filtration? I'll take better filtration any day and yes a filter does its best filtering when it is a little dirty.
Would be interesting to see results with an old-timey "Oil Bath" type air filter, where the air has to do a 180° turn in front of a bath of oil before going into the engine. I've been told by more than one mechanic, that those were 'the best'.
Thanks for the video idea.
@@karlelliott9254 I have '72 Dodge PowerWagon that was originally equipped with an oil-bath type engine air filter. I swapped it out for a cartridge type a few years back, and am wondering if I made a mistake doing so.
The trick will be finding an oil bath filter of sufficient airflow capability so it's a fairly even apples to apples comparison for pressure drop and flow rate.
Probably have to find an older junk yard engine in a hopefully common engine displacement so the air flow numbers more or less match. (like an old 350 with an air bath vs one with a round and one with a square filter.)
Karl Elliott my uncle used Allis Chalmers for years they were the best tractors money could buy on time,,, The last brand new one he bought was an AC 7060 darn good tractor however those Fords were pretty good also.
My 68 JD 4020 still runs fine and the sand separator has come apart so the oil bath is taking in everything and the plugs will look new no matter how long they're in it.
The 55 Chevy pickup was oil bath and it never used more oil than it did when it was bought used which was very little.
Test cabin air filter (regular and carbon filter)
Great recommendation!
@@ProjectFarm Perhaps you could incorporate a smoke test for cabin filters to simulate heavy traffic?
@@ProjectFarm Does the Toyota genuine carbon cabin air filter do a better job (at 10 x the cost) then the carbon air filter I can buy online? Does the Toyota genuine non-carbon fiber cabin air filter do a better job (at 5 x the cost) than the fiber cabin air filter I can buy online? I find that the genuine Toyota carbon cabin air filter comes with that new car leather smell embedded in it, but after a while it absorbs all the bad smells, particularly in damp weather with the cabin air on recycle in the city, so it ends up smelling pretty bad if you put the heater or air-conditioning on. Great at first, but needs changing after about 12,000 miles to get rid of the smell, even if it isn't clogged. The fiber filter has no embedded smell, and tends to absorb less smell.
Great idea especially for allergy prone people like myself. I found that many companies manufacture them but the fit into the filter bracket was terrible.
That I'd like to see and also do tiny carbon activated filters for cabin filtration actually outperform non activated carbon filters?
Have used Wix for years, but used to use Fram. Went over to Wix due to advice by knowledgeable mechanics and was told Fram was trash. Good to have confirmation in real world tests that I had received good advice. Nice video!
Thanks!
Wix is no longer Wix though. It got grabbed up by another filter company --- boo hoo. I also believe that the NAPA Gold line was Wix -- and if the conglomeration of them is true, then the NAPA gold is now suspect.
Bryan which flows better less restrictive between the fram and wix?
Seeing a lot of support posts and only ~1,800 patreon patrons. This is THE most informative, results driven, unbiased, genuine channel on this platform. Support this man if you can!
Thanks so much!
I dont know how you have the patience to do all this, your amazing sir. Plus I'm getting a good filter now!👍👍
Thank you very much!
@@ProjectFarm I think your testing method for particle pass through may have been flawed. K&N is unique in that it uses oil to catch particles. If you apply several years of particles (aka dump flower on it) all at once without cleaning and reoiling the oil becomes saturated and ceases to function.
Dude. 30 seconds in and I'm already in love with this vid. Nice work. I've been using the amazon brand on my powerstroke. I change it every 10k miles.
Thank you very much!
Ecogard brand. I've been happy with them.
Congrats on 1M subs if I didn't say it already. Absolutely amazing.
Thanks a ton!
Thanks!
Thanks for supporting the channel! I really appreciate it!
Project Farm’s testing is unlike any channel I’ve watched! I’d like to add two things:
1) K&N filters filter particles better when sprayed with the K&N oil, however it is a maintenance item, and I’ve had these run dry and ruin a Mass Air Flow Sensor before. However, they work great in the dust with oil applied.
2) Video Idea: Comparing resistance to flow through different spark plug wires, I. E. OEM, Performance wires, versus store bought/common brands.
Thanks for the feedback.
I've actually heard that the oil on a K&N can be drawn out as fine droplets, and clog up the wires on MAF sensor.
How true that is, I don't know....I have used K&N filters for over 15 years now without any issues.
Clean the oil off, you didn't ruin an MAF filter
The oil was already on it
Thanks for sharing.
K&N also will dirty your MAP sensor with oil and dirt if you don't take care of it. I been using WIX for years now. Great video as always!!!
True, I learned this lesson the hard way on a '98 Chevy by using a K&N and it was dusty were I lived at the time
The MAF may get dirty, true, but I've never had a dirty MAP sensor (in my experiences with Hondas).
In my most recent oil analysis from Black Stone on my EM2, there were 0 (zero) insolubles in my oil, and average was 1; I've got a K&N drop-in air filter.
@@crash_test_dummy_1 Yes you put oil in your air system it will go somewhere.
Thanks for the feedback.
One of my favorite channels I love watching this guy!
Thank you very much!
I'd love to see an oil filter test. Also curious how other manufacturer brands compare. Motorcraft, Mopar, etc.
Great suggestion!
@@ProjectFarm your gonna pour dirt in your engine next? lol
This is a great idea. I would love to see how the cheaper supertech filters compare to the fram and wix filters. I have heard that besides the top tier ultra synthetic filter, fram filters are crap. Wix has been known to be good overall, but i want to see what you are paying for.
Wix!
I really appreciate your hard work and attention to detail. I would also enjoy seeing an oil filter test around the same test parameters. If you decide to do an oil filter test, can you do one based on either the ls/lq style Chevrolet engine like in your suburban or even better one based on filters for a Cummins engine? Or even better, maybe both. I'm curious to see if there are any notable filtration differences between gas burner and diesel.thank you again for all your hard work and time. I can only imagine the r and d put into some of your test fixtures. Your efforts are much appreciated.
Again you have done a great service to the general public, I dont know why you dont have a TV show on Saturday mornings! Yes I do, You are fair and unbiased! Thank you so much for what you do. I am sure there are times you ask yourself if all the money and time is worth it. All I can say is Absolutely! And we appreciate all your efforts, Thanks gain.
Wow, thank you!
Fixing cars for 20years, and I have always believed that Fram was quality untill i saw this and the oilfilter test. Will never buy Fram again.
Buy the cheapest version you can then condemn the entire brand name.
Right on.
Chevy's are shit cars.
My uncle had a lemon in 1995 they're all junk
@@hotrodray6802 you sound like a cry baby, is that true?
Fram is garbage, always has been. Known that since I was 16, cut apart some oil filters and realized how terrible there products are.
I have avoided Fram wherever possible. I have heard too many horror stories, especially in relation to their oil filters.
Fram is capable of making a good filter. Their orange ones (PH part numbers) are garbage. Their higher tiers are much better, but the build quality and filtering performance of their cheapies always gives me pause.
I appreciate you did this. I researched filters online and decided on the WIX. I am glad to see the Purolator is also just as good.
Stupendous! This is information unavailable anywhere else, and it's VERY useful. Man oh man you really do an amazing job here, and it's HUGELY appreciated!
Wow, thanks!
The biggest problem I've seen with oiled air filters is oil coating of the mass air flow sensor element on MAF equipped engines. It's a gradual process (and usually accelerated by someone over oiling the filter after cleaning), but can result in a fine coating of oil and dust on the sensor element. For hot wire sensors this insulates the sensor which can result in an artificially low airflow reading creating a lean and overadvanced condition. Nothing a $10 can of MAF cleaner spray won't fix, but it pays to be aware of it. Speed density cars (or non-hotwire MAFs) need not worry.
Thanks for the feedback.
I buy a house brand maf cleaner for 3$ and for an average time of one minute to pull the sensor and blast it clean it's good cheap preventative maintenance.
Same with turbocharged or supercharged vehicles. Run enough boost and you’re liable to oil up a wheel or screw. Which then could allow particulates to cling on and score up a compressor
Church Automotive Testing Dyno Tuning 99% of the time the reason people have problems with their oiled filters is cause their over oiling their filters. I have a 95 Dodge Ram with a turbo charger and a 2018,Kia Soul with a turbo charger among many other vehicles previously with K&N air filters and have yet to ever have a problem myself. But the ones I’ve helped that has had problems have always sprayed way too much oil on their filters. K&N air filters are only supposed to have a light layer sprayed on the filter. If your sucking oil on to other parts in the engine then it’s most likely been oiled too much!
This is gold. Let us all know when the sore loser companies start coming after you, we got your back.
Thank you very much! I greatly appreciate the support!
@@ProjectFarm You are the only UA-camr i trust when it comes to producttesting.
I would bet money that you wouldnt trick us!
Also i love the the unbiased conclusions.
Btw. Could you please make your graphs easier to read or nicer to look at. I mean i understand them but they are unpleasant to look at.
ALSO can you please make a rating home many times which brand won in the testings??
Don't the k&n filters need oiling before use? I used them in my bikes for years. I've never used them on cars.
@@Adrianyoutubing it comes pre oiled
@@Adrianyoutubing yeah after the initial use... they can be cleaned and then re-oiled.... kind of a pain actually.
Wow thank you so much, this test has changed my perspective on k and n filters. I have these filters in all of my vehicles, that will now change. God bless and be safe
You are welcome!
You should test “cabin” air filters next!
agree Plz do the cabin air filters test!! 3m and bosch
Agree. If especially like to see a comparison of the activated carbon cabin air filters with regular paper cabin air filters.
Fram has a nice one I've been using with Arm&Hammer and carbon. Very good, neutral smell.
Agreed. I cringed when I asked how much mine was at the Honda dealership. It was still really expensive from online OEM dealers.
You guys have cabin air filters 😱
I would like to see you do a similar test on auto oil filters. I searched your channel and did not see a video like this. This air filter video was great info!!
Great suggestion!
@@ProjectFarm Oil filters are another beast that comes in different forms. Amsoil makes a full flow filter that's very good but when used with a secondary fine filter is unbeatable. Bypass oil filters can't be beaten. Some big dirt equipment comes with full flow and bypass filters.
That would be very interesting
He done one
I was actually searching project farm for an Oil Filter video, but couldn't find one, so just decided to watch this one.. again.
Very fascinating the "contraptions" that you come up with to perform your "experiments". Also, the various instruments that you have bought or made to perform these tests is incredible. Thank you for making and sharing this video.
Chuck Hall Yes i “agree” with your “observations”
Many thanks!
Thanks!
I love coming back to this video because thanks to you i discovered the best overall engine and cabin filters...WIX 💪💯
Thanks for sharing.
From my 8yo son: “He should test cheap and expensive tires”
Great video idea! Please say "thank you" to your son for me!
Smart kid
I would give patreon support for that, given the number of tires i go through.
Tyre Reviews is a great channel for that.
@@tobasb2 I prefer Project Farm. He keeps it simple and honest. I am by no means saying the channel you mention doesn't, by the way.
Fram's slogan is "Filtering out the nonsense"
I think they should give the slogan to Project Farm
Thanks for watching!
