Why does Bosch have such small inlet holes?!? I mean Bosch is the winner here just given the sheer numbers and the filter media, but why ruin all that with such small inlet holes? Anyone know the benefit of small inlet holes and why they designed them that way?!? Like why risk depriving engine of good oil flow with those small size inlet holes?
I'm not very good at math, but I was told the inlet holes added together will not be smaller than the outlet hole on any oil filter. Like I said I don't know how to measure the circles and figure that all out, but I prefer bigger inlet holes also. I'll pin your comment and see if someone can explain it better.
@@WhipCityWrencher Thank you very much good sir. You see the math is a little more than just the sum of the area of all inlet holes being slightly larger than that of the outlet hole. It is also about building pressure BEHIND the filter to force the oil through the filter media. More surface area means more resistance to oil flow. Meaning if you have more of a surface area for the filter media, which is what we have here in case of Bosch filter, you will need a higher INITIAL pressure to push the oil through the filter media before it even reaches the outlet hole, because more media poses more resistance. So you would want larger holes to accommodate more immediate pressure against the filter media to allow for that higher initial pressure. Otherwise, you would ultimately have a bit of hesitation in flow of oil, specially at engine start up. This can easily be remedied with larger inlet holes. I really don't understand what Bosch did here with more media and smaller holes. Those two properties don't go together. More filter media should mean larger inlet holes regardless of the size of outlet hole.
I agree... wasn't for the small holes it would be a great filter
Denso & the discontinued Honda A-01 filters has round holes too. The holes on Bosch look really tiny too. Nothing scientific here, just making a statement of what I see.
@@XerxesTheGreatOne Bosch has amazing engineers, and I think the opposite is true; smaller holes will help build that initial flow better than larger holes for that. It's pretty basic actually, if you use your thumb to restrict part of the opening of a hose, it comes out under higher pressure, if you use a bigger hose, the water would come out at less pressure.
Good balance between serious work and playful fun! Check out the space between filter and can for free flow from holes to media. Hmm!???!
Very thorough and concise- thanks!
You're Very Welcome👍and
Thanks for Watching😊
best compare ever !! ❤ continue plz
Thank You👍
Both are great filters!
I love the prices on rock auto, but you have to watch out for Shipping costs.
We have explored the idea in the shop of ordering mass filters from Rock Auto to get those discounts.
Need to watch out for those parts made in China.
Another great video! Thanks
You're Welcome! 👍😊
"I love the prices on rock auto, but you have to watch out for Shipping costs."
Great point. If you buy individually on RA both these filters significantly more because of shipping costs. Normally have to buy lots of at least 6 to get any kind of value. I don't go through filters that fast. If you try to buy them elsewhere, get a better idea readily available individual price. My.02
NO !! They both can't be equally "great" -- too many differences for them to be called "the same".
One of them is clearly much "better" than the other -- and each one of us has to DECIDE which oil filter meets OUR OWN INDIVIDUAL requirements, and buy accordingly.
RockAuto has the best parts prices -- they ship by FEDX -- it's good, but relatively expensive.
Bosch is the clear winner. Also more threads. Wix build is very sloppy.
The quality and performance for both filters is great. However, because the bosch filter has more media, it has more capacity. The only difference is maybe having to change the wix sooner. If you change oil at 3K then the capacity difference is irrelevant. it really comes down to price. The bosch looks like it will last for a longer drain interval beyond 3K. Otherwise, both are excellent choices..The best part of these filters was the comparison lol! Great job!👍👍
Thank You!
Thanks for your feedback and Glad you liked the video.👍😊
5k is the new 3k
@@Mr.G626 True. But lots of folks still drain at 3K no matter what the "experts" may say. It really depends on what you drive, the type of oil used, and how. I know of some guys that go racing and change oil as soon they are finished. I personally change every 4K.
Nah. In a well maintained vehicle, never come close to either filter's "holding capacity". Either will work fine for ~7500 miles 1 year. And ~5k miles, easy for both.
@@faxmen09 Oil filters over time and mileage deteriorate and lose their effectiveness. Hot, high pressure oil constantly passing through the media eventually increses the porosity allowing larger particles through as the dirt / contaminates build up. So even if the actual "capacity" limit is not reached through good maintenence, oil filters should be changed regularly. Thats one of the reasons Whip's filter comparisons are so awesome. He shows the actual thickness of the media and allows the veiwer to get a good idea how clean their engine will be kept with a given oil filter....
I would probably go with the WIX.I like the coil spring better...
Thanks for watching and your feedback👍😊
Well, another study in futility since this is made by Bosch - Mann - Hummel that bought Purolator, that also makes Motorcraft and others in the SAME plant. Funny, huh? Like the coil spring? get a Motorcraft.
Just about everybody says "I like the Coil Spring better!" -- but the FACT is, that they dumped the coil spring -- because, according to FRAM, the Leaf Spring does a BETTER JOB of holding the element firmly in place.
Notice that the most expensive oil filters (Amsoil, Royal Purple) use the Leaf Spring exclusively.
Thank you sir.
I have used both Bosch and Napa Gold (wix). I wish wix and napa still used the threaded or upfront bypass. It seems like the only concern with all these filter companies is the bottom line. I know I would be willing to pay more for a filter that was hands down the best you can buy. Maybe I am in a pretty small group however and the filter companies have to sell their product to the masses to keep their doors open.
I agree,
I like the upper bypass also and would be willing to pay a little extra for it.
Thanks for your feedback👍
Thanks, same here…. Though, actually went to BOSS PUROLATER, Filter ON MY **2007:CANYON 4CYL/,@141,000 ++, :& it actually purrs QUIETER (MOB 1 SYN), if possible,( thiugh just got it out of Shop for new Alternator,& Replace one year old Interstate Battery, waiting on “SERP Belt “, as only 20K on it)…. Etc… Usually NAPA GOLD( WIX),GO TO normal distances.
Well, another study in futility since this is made by Bosch - Mann - Hummel that bought Purolator, that also makes Motorcraft and others in the SAME plant. Funny, huh?
I think the Bosch is looking pretty stellar and have been running wix for some years now.
Thanks for sharing and your feedback!👍
another great comparison.thank you again 4 your work kind sir..🌚👍
Thank You!
and Thanks for watching, Glad you liked the video.👍🙌😊
I've used Wix exclusively for decades without a single failure. Since the Wix has less filter media, it should be changed more often.(which I do anyway) I think the Wix has better construction, I just wish that they would match Bosch in media, then it wouldn't be close.
Exactly right... I change oil every 3500 to 4000 miles but I am old school as a retired mechanic
Between the 2 of them, I would choose the Purolator Boss or the Fram Ultra Synthetic, and as an annoying guy...lol. I used to use the Bosch Premium, though.
I thought both are made by the same parent company?
True, Purolator makes the Bosch filter. Purolator and Wix are owned by Mann and Hummel.
I like both but I'm staying with Wix xp or napa platinum. At least until you find a better one. Thanks again for another fine video.
You're Welcome!
Thanks for watching👍
Royal Purple 💜
@@TranslatedAssumption I do like royal purple oil and filters but I can't find them as easy as napa platinum. And Amsoil is even harder to find and more expensive. I recently tried a microgreen 2 micron filter but now ebay sellers want 40 dollars.
FYI the Napa Gold/Wix Regular filters down to 21 instead of 35 for XP/Platinum.
After watching again... still say the wix and only reason is the coil spring.. I have used a few bosch before with no problems still perfer napa gold and wix... the bosch I bought at menards around 3 a piece on clearance
Thanks again
You're Welcome!👍😊
One detail to note. It makes no difference how tightly the gasket is mounted on the filter. If it's inside a recessed lip, and it doesn't fall off when you shake the filter, you're good. It's not going anywhere.
Another great video! You are definitely an expert when it comes to oil filters. Like 74! 👍
Ha Ha,
Thanks, Ela
but I'm no expert, not even close. Learning all the time.
Just trying to make some informative and entertaining videos.
Glad you liked the video.👍😊
Well, I still think of you as an expert in this area. 🙂
► Oil Filter Friday,
Watch a New Automotive oil filter inspection video every Friday on this UA-cam channel.
Wix all the way
As much as I want to give it to the wix’s if I had to choose to put it in my car it would be the Bosch only because of the more filtering media.
Yeah, it does have a lot more filter media.
Thanks for your comment👍😊
Sadly for most Korean cars bosch will not work and will damage engine due to incorrect bypass settings...new filter lasted under 400 mikes before caused ticking and noise on startuo...replaced w oem and no issues
I'd have to give the edge to the Bosch.
Thanks for watching and your feedback👍

@@RRaucina Not funny, Richard -- NO Ha-Ha-Ha -- just normal business practices in the Oil Filter Industry .
We have to learn to adjust to a Global Economy -- because the Internet has made the World a much smaller place.
I like the WIX.
Thanks for watching and your feedback👍🙏😊
I've used Bosch in the past. Vehicle was a 2016 scion ia I had a situation where the Bosch filters loosened through the duration in use. 1st was a workshop filter figured it was a cheaper filter but the premium Bosch did the same. Thanks for your vids much appreciated. Wix.. ac delco.. kn.. Mobil 1 puts out a nice filter.
Thank You! Glad you liked the videos.😊
I would not assume both filters use the same media. "That" Wix is made by Wix in Gastonia NC. The Bosch Premium made by Purolator in Fayetteville NC. Wix beta (on Wix site) translates to 95%%20 microns, BP box rated 99%@20microns. Depending on price I'd use either with no problem. Also I don't get in a twist because of louver use. As long as open they work great. Want to test, remove media and put a light source down tube. See all the openings. As the Wix made in March, I'd be looking for some M&H changes on newer stock, like shown in your other Wix vs NG video. Thanks for video.
You're Welcome!
Sorry, I prefer holes, I'll use filters with louvers but I prefer holes.
Thanks for your feedback👍😊
@@WhipCityWrencher No need to be sorry, to each their own. I just haven't seen any scientific basis that holes superior to louvers. As long as louvers open, provide at least equivalent flow. Same goes for counting inlet holes. More does not equal more flow. No filter can flow more than the inner area of engine block filter mounting stud. Find the area of all the inlet holes, they will be equal to or more than area of mounting stud. That's max flow.
Well, another study in futility since this is made by Bosch - Mann - Hummel that bought Purolator, that also makes Motorcraft and others in the SAME plant or a sister plant. Funny, huh? Global consolidation
I just bought 4 Bosch filters #3310 for 5 bucks on EBay. I was buying Fram pro series FPS 3597 on close out , but they are twice the cost. Bosch ftw!
Thanks for sharing!👍
I don't want to be nitpicking but the Wix had some rust on the base plate, I really like the bypass of the Wix and the spring, but even with less media I still go for the Wix
Two great filters!!!
Thanks for watching and your feedback👍😊
Long time Wix user (fell for their marketing) and now very disappointed at their tiny filter medias. The Fram PH4967 cross reference with 81.9 sq-in has 75% more filter media! Both are 95% at 20 microns as well.
Do the Wix synthetic vs ? I have a Ram 2500 Diesel
I have a couple of diesel oil filters showing next month April 22nd.
sloppy with the glue, really? It's the filter material and the amount of it that matters
I dont like sloppy filters.
Thanks for your feedback👍
Great job, and thanks for the media measurements --
The Bosch media is 27 % longer (stretched out).
The Bosch media is 35% wider (end-to-end) .
The Bosch media is 74 % larger (total sq. ins.)
Due to it's much larger overall size, the Bosch filter can hold a lot more dirt before clogging.
The coil spring looks "nice" -- but it really covers up for the fact that the Wix media is much smaller, and will most likely clog before the Bosch reaches it's dirt-holding capacity.
The narrower Bosch gasket can withstand more pressure before leaking.
That stamped spring that gets all the criticism is the real hero, as it allows for greater filter capacity.
The Wix uses the Inlet-End By-Pass valve (a la Motorcraft FL820-S), which is definitely the preffered valve location.
For me, the ideal oil filter would be the Bosch with the addition of an Inlet-End By-Pass valve.
The famous 95 MERC runs Pennzoil Ultra Platinum, 5W-20; Bosch Premium Oil Filter # 3410; and a FILTERMAG #SS365PR.
Oil & Filter changes at 5,000 miles. And NEVER any oil additives -- period !
Thank You!😊🙌
WTF !?? Why is the name "Vladimir Karpov" on MY post, with MY avatar ??
It's not nice to f**k around with good people.
@@SlikLizrd I'd blame the Fram website.
BOSCH is superior more filter media wider as well that's the business end of things.. BOSCH all the way
Thanks for watching and your feedback👍😊
Sadly no...causes more restriction which equals more engine wear and failures
I don't use bosch because they always have tiny inlet holes and that is a flow restriction. Otherwise they are a fine filter.
Thanks for watching and your feedback👍
And bosch will not work w hyubdai and kia cars due to poor flow characteristics that causes engine ticking..which equals poor oiling of engine= premature engine failure
BP flows fine. No filter can flow more than inner area of engine block filter mounting stud. Guaranteed total area BP inlet holes more than area filter mounting stud. As for Hyundai use comment, poppycock. Total internet blather.
@@faxmen09 Isn't the restriction of the media more than holes, and or holes/louvers in center core?
Allison trans spin ons recently changed from holes to louvers after 15 years and the tech at Allison said either are fine. I've used both on our fleet and could never tell a difference.
@@GT-mn3bx Here's a 'fact' for you. The engine itself (oil galleries) is ~15x more restrictive than the oil filter. Louvers or holes, both work just fine. And consider this, there's always far more louver openings than holes in a center tube. Fact. One can have a preference for one or the other, but that's bias, NOT science.
The Wix would win with its coil spring and upper bypass except the filter media is much less than the Bosch.
Thanks for watching and you feedback👍😊
Wix filters will work on hyundai/kia cars...as long as it is changed at proper intervals...once the bypass valve sticks engine gives into bypass mode and you loose power....then boom blown engine...secret change regularly
Technically made by same company but different designs
@@johnervin1474 That's true of any filter. They need to be changed before they reach the end of their life.
@@WhipCityWrencher how can you tell if an oil filter has gone into bypass mode? When I cut my filters open after the OCI, the pleats still look straight up & down and intact (no warbling), and the bypass spring still feels tight.
I think the bosch is made by tearolator. I’ll stick with wix or fram
Thanks for watching and your feedback👍
Too bad Wix changed their design
Yep, sadly it's all about $
Thanks for watching👍😊
@@WhipCityWrencher OF COURSE it's all about the $$$ , Whip !! --
THIS is what our American workers are competing against:
ua-cam.com/video/ZXp7aGQ7n38/v-deo.html
YES. "Gasket Retainers" -- definitely NOT "O-Ring Retainers" -- these are oil filter GASKETS, and are NOT shaped like O-Rings. They should be referred to as "GASKETS".
The measured thickness of the gasket is not important, so a "thicker" gasket is not "better" -- what MATTERS is the amount that the Gasket sticks up above the edge of the Cannister.
In this instance, the thicker gasket is a waste of rubber, because it's much thicker than it needs to be.
At first glance, the thicker gasket seems to be the right choice -- but, all things considered, it's a WRONG choice for our rapidly-deteriorating environment.
What gets overlooked is the excellent performance of the Bosch FILTECH's glass-filled filter media, which is often incorrectly called "paper" or "cellulose".
Scroll down you'll see the Gasket O ring? www.rockauto.com/en/moreinfo.php?pk=90067&cc=1135448&pt=5340&jsn=525
@@WhipCityWrencher NO. The "info" calls it a "Gasket O-Ring", but a PICTURE of the inlet end of the ACDelco filter shows that the gasket is NOT an O-Ring, but a square-cut gasket with a flat sealing edge.
There is a technical definition for "O-Ring" -- and the gasket that is used on almost all spin-on oil filters DOES NOT fit the definition.
An O-Ring has a CIRCULAR cross-section -- these oil filter gaskets have FLAT sealing surfaces -- If there is NO circular cross-section, it's NOT an O-Ring.
I noticed that the "Hecho en Mexico" WIX filter has the obsolete Coil Spring -- but it has the coveted Inlet-End By-Pass Valve.
I'm wondering who holds the patent on that Inlet-End By-Pass Valve !??
