- This is the Air Box Mod we've been doing for years.
Not only does it work well, It's cheap.
K+N PART NUMBER: E-2435
No worry about heat soak, no worries about standing water either.
Enjoy and comment below.
People don't give enough credit to OEM-designed airboxes. Especially Honda, who by and large, does them fairly well.
Absolutely correct. Mine in my Si is bone stock with a K&N drop in. Just a few tweeks are needed to the stock air box and boom, you have a cold air intake.
Samco makes a hose for the factory airbox, I wonder f it improves HP,
@@iivv_nn No. Honda pipe isn’t ribbed internally so a different pipe makes no difference whatsoever
Have you seen the rsx intake? Heat soaked all the time, I had to go completely custom and now no more heat soak and gained power...so no credit from me, I honestly don't understand why they did that im assuming they rushed it out??
the RSX may be one of the worst factory intake boxes.
Don't worry John you are not click bait material, I will watch all your vids till the end.
I don't do 'Click Bait' The thumb nail is always from the video and we never mislead you about it's content
I'm so impressed with your knowledge and attention to detail. You run a top notch shop.
Did this Mod today, Took about 45 minutes using a Dremel Tool (without removing the air box from the car) Thank You very much for the detailed instructions!
DG DG Great. Thanks for the post
Trying to convince my mom to buy an s2000 since she loves my integra.
Great info. I agree these motors naturally aspirated are almost perfect from the factory.
No, Put a LHT Kraftwerks kit on it...Then it's 400whp perfect ;)
LHTPerformance I agree. Keep up the content is great and informative
LHTPerformance You tease..
@@LHTPerformance haha!
Old video, but glad to have honest information on the s2000. It's been over a decade since I've owned one, but am getting back into one this week.
Best intake for me.. I've done this mode a couple of years ago combined with the cooling plate and the results are very good
Honda’s are great cars all around. I can never complain when I’m behind the wheel of one!
I’m using a Cosworth air filter which is almost the same as K&N, but it’s blue and it doesn’t need to be oiled. It’s working great for a good price. J’s Racing is selling it as a rebranded part for more than doble the price. Stock airbox is definately the best option for the S2000 if you want it to be versatile
I wish I had seen this video a couple of days ago! I had the airbox out to replace my radiator. No matter, it's an easy job.
Love this mod John!, psyched thanks for doing this and other proceedures!!! just bought my K&N filter, looking forward to do this mod to my 05s2k over the next few weeks..getting ready for spring up here in NE....
Gary Chalifoux Great, glad it helped 👍🏻
Hey John?? when I did the air box mod, my OEM filter didn't have a retainer ring? does this mean previous owner forgot to put it back on? or does the s2000 OEM come with a ring? do you have a part number for me to buy one? thanks
This is awesome and definitely helped me make my mind up what to do intake-wise! Thanks for the video! Liked and subscribed from an S2K owner from the UK 😁 🇬🇧
Sweet ! Thanks for watching
Niceee! Thank you very much! Please more of mods like this!
I bought the K&N CAI and noticed heat soak. I will most likely go back to stock and do this mod unless I supercharge this spring.
Great vid!
Awesome tip! Working on the mod as we speak. K&N intake out, original box back in. Waiting for better weather here in The Netherlands before i can test on the road unfortunately :( Great video's guys and girl!
Great info! Looking forward to getting my S2K into you one of these days!
Ryan Abenante It’s a lot of car for the money
I just did this to my car sans blocking the air outlet. It was incredibly easy. Thanks!
How did it sound afterwards?
Super nice video. Beats some of the misconceptions about intakes.
Anyone else notice that giant bug when he was removing the clips... Or was that just me.
yeah that fucker is huge!
when I purchased my car(used) it came with the k&n filter and tube ..I'm thinking of going back to stock and doing this ..
that hondata tune really helps the vtec transition
This was the first mod I did to mine 👍. I've since replaced the OEM airbox with a K&N FIPK for even more noise 😁
Rob Coleman then you're just allow more heat soak in, you need the stock air box
But what about the noise!! 😄 I can live with a very occasional bit of heat soak, never been too much of an issue for me.
He could live in a cold place.
Turns out the Honda engineers knew what they were doing lol
Thank you for the tip! I'm buying the s2k my dad and I worked on when I was a kid. This is a nice blend of stock/performance improvement. Love your videos may end up taking it to you for a supercharger in the future!
I'm addicted to all your S2000 advice, my only wish is that you were in the UK. It's a bit of a long drive
Dale Broughton lol. Thanks for watching mate.
I love these Wednesday tutorials! Definitely trying out this mod on Saturday, looks too easy not too! Thanks!
You guys are awesome thanks for the airbox tip, I will try it on my 02.
LHT! I enjoy all of your videos thank you!
T hanks for sharing the info. Makes me want to go back to stock on my project Celica if I could.
Sounds great.. I've been doing it for a year now.
Is it more quite???
That was interesting. I like short rams, but only because they save me a lot of gas in the winter, lol. :) Come check it out.
I would love to see results of the airbox mod on a totally stock motor.. no header or tune, just more airflow..
WezleyB I tried that. I am not that sure but the sound becomes larger
It's actually deceased airflow with the mod, motoiq did proper testing and saw pressure drop. Probably because Honda engineers knew what they were doing when building that intake, it isn't too make it quieter but to decrease turbulence and increase airflow.
I was thinking about cutting just the initial section so there are still "walls" to provide pressure against.
@@sergeberlina8600 Not surprised, there are too many 'it works' claims that are unsubstantiated.
I’ve noticed that! With my aem v2 the car feel different depending on the weather! Great mod I’ll try this
Norrr R Exactly. The cold air intakes makes power on the dyno after a cool down. But on a track they loose power. Like I mentioned, looks at what the race teams use.
Wish you had some pricing on certain packages in your website. It’s much easier to have a ballpark figure and know how money we are looking at. Love the vids. Would luv to bring my car in.
Really nice of you to spend the time on a non-revenue video for everyone. I've got an '07 bought as crazy turbo with Greddy Ti Catback single & Flashpro but am back to all OEM (at great expense) running one of the OEM tunes in the FP. You added a Skunk header to this '06+ with the mod and a FP tune and got great results. Most dyno tests show reduced HP/TQ with ANY bolt ons so very interesting. Q's1: You didn't change the injectors? Just airbox, header? Change to exhaust downstream of header?
Assuming I do exactly what you did (need to know above about Skunk plus....what?) do you sell your tune?
I have an unknown header and was considering putting the Greddy single back on either with OEM header or the generic header to save weight but 70mm is way too big for OEM "flow." Would I be able to get it in "balance" with the airbox mod and perhaps slightly bigger injectors plus tune for as much or more than you got?
Second one. I have an '02 AP1 track-only car that is all OEM except a junk pipe and filter it came with. I'm thinking about buying the OEM airbox for it, putting on that generic header and either opening up the exhaust or using the Ti-Greddy but diff mounts than my AP2. I have an AEM V2 I removed when I bought the car, never have used/tuned with one. So again, I'm thinking I would need bigger injectors to "balance" the input/burn/output. Your thoughts?
Just bought and install my K&N air filter! I love the look of the stock airbox
So much knowledge
Keep up the great content!
Modern airbox help with performance.
The swiss cheese mod it's the cheapest way to get more air into your stock air-box,you should try it....
Its very good mod but you are very wrong with one thing. This external chaimber is a air wave resonator. It reduces air waves inside the intake witch improves torque and throttle responce in mid range rpm. It has small impact on intake sound so I would strongly recomend to leave it connected.
Jan Nowakowski We’ve tested this many time and talked to race teams. It makes power. The chamber is a resonator to reduce drone 😉
Based on what testing did you come up with that conclusion?
Serge Berlina Repeatedly more consistent hp, slightly lower iats and positive consistent fuel trims .
That is VERY COOL! Any chance there would be a mod like this for the 2015 Civic Si? I’d love to remove some sound dampening and unleash more of the vtec growl! Thank you for uploading this!!
Hey LHT, LOVED this video. I'll be doing the Airbox mod tonight! Question: I have a 2005 AP2 and want to replicate what you've done here (flash, air box, headers). Can you recommend a tuner in the NY, NJ, CN tri-state area with whom I might have my ECU tuned as you have here? And what ballpark should I expect to pay? Cheers, C
great tip...thanks
Thank you for your information!
Done this on both my s2000's my fav cheap mod
Timsta Woahz totally stock s2000. Would engine check light is on because of increased air intake flow in?
Do you really notice better throttle response or is it just placebo?
Does it make a difference in sound is it less noisy?
Check out that bug in the lower right starting at 4:11
At 8:20 if mou make the snorkel wider (so more incoming air) there would be no gains?
I just got an S2000 so your videos have been great, thanks! What Hondabond did you use, red or blue?
A lot of people blow money on a pipe and air filter, call it cold air, and say it adds tons of power. Engineers spend millions developing engine bays, they know what they are doing.
Their goals are emissions, then efficiency, then power. If you want to tip the scale away from their goals to your goals, modifications can with your goals. If your goals are the same as the engineer then the job is probably done.
Eh that's not really how it works. ENgineers spend millions because they need to meet thousands of regulations. In that case, aftermarket companies spend lots of time tuning and testing different intake systems for one purpose and that is performance. Honda did a really good job here but that's a misleading assumption that it's the case for most cars.
dont forget the engineerz also wanna make sure its not too loud for granny or dads midlife crisis car lol
Read up on motoiq article about this very mod and come tell me "cutting shit out makes power because they tried to dampen the sound for Grandmas"
Serge Berlina You’re exactly Who I was talking about when I said Dads midlife crisis car LOL
John do you have an opinion/done any testing on snorkels for the OEM airbox? (For example the spoon sports snorkel)
I’ve seen them used in many top builds (r walker from evasive motor sports for instance) but wanted to know your take?
Eric Walsh I think they are a great idea. It only improves an already heart design
John, do you suggest I put the air box cover back on when I’m done or leave it off?
The_Thrillist84 Putting the lid back on will allow the intake to draw cooler air from the front (where designed) and from the hotter engine bay
Just a thought, the air diverter on the top box, 2min 30. Is it not worth leaving that in so it channels the air straight towards the air filter. Maybe totally not understanding it but just an idea I had from yet another great video from the boys and girl at LHT. yours David
You forgot to cut all the fins out. That will help it to sound even better
Nice show good info! Thank you from VT
Haven't read any comments giving insight on the Password JDM full induction kit and where it stands with the stock airbox so I wanted to see whats your intake on it? Ive also done my own experimenting on my stock box using a scan tool to measure air temperature before and after taping the stock box and tube with reflect-a-gold tape. on a 102 degree vegas day I was 5 degrees cooler at idle and 10 degrees cooler while in motion. Ive recently put on the Password snorkel to factory box and instantly noticed my second gear was breaking traction a whole lot easier but like all good things I think my PCM wasn't having any of it and said: NONONO! and remapped it taking the fun outta my new found power. I mean I feel more power than what it was before but not as much as the first day of install... Stupid computers and their learning apparatus! lol... ill will be doing this mod to see what power I can get but I have a feeling that the damn PCM will take my fun away again hahaha!
That is all going to help. The cooler air you can supply the engine = more power.
Make no mistake your not going to make much genuine power increase by replacing the filter. Lastly you've removed the resonator and now disrupted the air flow ie the smoothing and resonance and effected performance slightly.
I have a Celica SS-III. And i also noticed that removing the Resonator made less power, at least that's what the butt dyno told me
A true test is on the track. And yes, It makes power. Of course, I'm not trying to sell them so I'm not looking for anyone to agree. ;)
Has anyone here sent off their oil for analysis after using the K&N filter. You might want to check for high silicone.
6:27 to make this good use 2 compound glue. This will hold for years.
dang 229whp is good numbers for the NA s2k, I only made 205whp on my ap1 with minor bolts on with stock ecu.
That's about right. The AP2s make a little more.
Great video, wondering what is LHT's opinion on the snokels for OEM box.
Interesting video. I'm currently trialing the K&N FIPK setup vs the standard airbox with a K&N filter.
The FIPK has been on the car for the last few years, but the induction noise is excessive to other people - they find it boy-racerish when being overtaken.
The standard airbox is a LOT quieter, but it's lost some of the Jekyll & Hyde nature of the VTEC switch at 6000 rpm.
Power difference isn't much, though I haven't measured it - I suspect the FIPK may have a few more bhp, but it's easier to drive the standard setup quickly for longer without being obtrusive (and there's less heat soak).
Does anyone have an idea of the relative induction noise levels of the FIPK vs the airbox mod?
Thanks...
Would cutting off the Helmholz resonator (air resonator) from the side off the airbox cause any issues? It seems you could free up some space and reduce weight with this a tad.
What's your take on the AFE intake for the s2000? It's virtually the same design as OEM with a much larger filter and tapered intake tube , it's got to be slightly better than a modded stock box
It looks like a very good design....But...Is it better than this ? We'd have to dyno it to really know.. This is the price of a K+N filter. We charge $100 for doing this with the filter included.
This is definitely the best bang for the buck no doubt. I have a modded box on my car currently and 3D printed the piece to cover the resonator section. I just picked up the AFE kit and will be putting it on in the spring, I wont have back to back dyno results so it may not actually get any gains, but in theory it should
by far one of the best things you can do for power is get an exhaust for the s2000. when i got my ap1 the last owner did the airbox mod but i finished it off by blocking the little port under the filter and also tried cleaning up all the little fins inside the box. i think a better thing to do for intake other than going with a coil air setup is getting a cooling plate from passwordjdm. they go for about $230 to $250 for carbon fiber or carbon kevlar and you can get it for the cutout for the ram air scoop or without the cutout.
@LHTPerformance thanks for the video. I performed this mod on my own using the AFe dry flow filter and I noticed a little bit of difference for sure.
When the car is on the Dyno, what's that high pitched metallic ringing sound in the upper revs? My car does the same.
Could you remove the noise reduction box, not just block it off? Would save some weight.
John
what i would like to see is repurposing the airbox when you go topmount turbo manifold
Let me get this straight, this makes more repeateable power than the K&N FIPK?
Yes.
IMO, the carbon fiber engine bay panel and carbon fiber air intake mods are not good to vehicle. They restrict air flow intake volume. My suggestion is to make uneven place more even. It's like vehicle bottom and some manufacturers make flat bottom panel in order to increase downforce of the car.
Have you spent time in the north of England? You've got a particular twang to your accent.
I was born in Yorkshire England and moved here at 23
@@LHTPerformance Ah right! I thought i picked something up haha.
a cooling plate combined with this mod would actually help , or would cause less air flow? could you please advise?
Very thorough post. You can’t go wrong. Has this car had the air pump and EGR removed? Thanks
S Cooper No, it remains stock.
I’ve noticed that the induction sound is a lot louder when I leave the cover to the air box off, am I going to heat soak if I leave the cover to the box off?
Is the K&N better than the oem filter?
How does this compare to the Comptech intake system which has its own closed air box. My S2000 came with the Comptech intake and Im not sure if I should take it off and go back to stock with this mod or keep the Comptech. The one thing I don't like with Comptech is the filter type and media
Unfortunately I did this and now the sound is not as nice as it was before.( I am comparing the sound with my friends completly stock S2000 with no air box mods, while listening to both cars from outside approaching me and accelerating or flyby)Now I need to buy an other oem air box or other brand... Honda is not stupid with that box its all about air flow and sound.so Keep factory box with no mods or buy a really good one aftermarket. Thanks.
Το έκοψες και ακούγεται χειρότερα ? Είδες κάποια διάφορα???
@@user-on3sk3xo6o μην το κοψεις φιλε. Κανει τον ηχο πιο βαρετο. Και δεν το κανει πιο γρηγορο. Καλυτερα ασε το οπως ειναι η αγορασε ολοκληρο intake aftermarket π.χ. mugen, j's racing, password jdm ή αλλα. Μετα που το εκοψα αγορασα αλλο μεταχειρισμενο κουτι.

NICEEE!!!
have you ever used any type of insulation inside the box after you have modded it, to further keep heat out?
Hand Banana Back in 1999 when the S2000 first came out we built a carbon thermal shield to insulate the head from the box. It got ripped off a couple of years later, we made. 100 or so and it worked very well.
Is there a similar airbox mod for a 96-00 Civic for the induction noise?
whats the part number for the metal ring around the filter?
Nice!
What is the purpose of removing the funnel from the top of the intake box? Wouldn't it be beneficial to leave it?
More sound but you right
K&N Filter better than OEM filter in this modified box?
Does the regular OEM intake filter work?
It does of course work and it’s factory installed. The K+N is a much a higher flowing low restriction filter.
@@LHTPerformance Thank you. I was just reading and some people said the K&N allows for high air flow but does not filter particles as well. So I was a little conflicted. Seems like it's worth the improvement based on your video.
@Jetkid03 It’s a great filter to use on the older cars that doesn’t run a MAS air flow sensor.
Can the cavity on the right be cut off?
How can I get one of the s2000 t shirts seen in the back at 9:04?
I'm probably wrong but do you have a British twang to your accent? ..Other than that, great informative video..Si..UK.
Yes. I was born in England left in 1993. Thanks 👍🏻
I thought so mate 😁..I'm in Manchester. ..unfortunately theres something's you just cant get rid of🤣. ..Si
How much heat does it create using this air box mod? I would like to know before i could made this approach, anyone?
Wait so doing this doesn’t hurt the car’s performance right ?
Hi there. How can you prove that this air box mod actually works?
Odysseas Lambrou I have nothing to gain. I’m not charging for this or benefit at all, I’m sharing the info. It’s quite simply, it basically take an excellent design and makes
It more efficient.
Do you need to remove the bottom air box to cut the partition flap off?
Pwillig I would, just makes it easier
so I just want to be absolutely sure. It is safe to drive in the rain with the air box mod?
adrian casas Yes. We get more rain than most and tested it many times. You cannot drive into standing water of any kind
Can you use the oem filter or do you have to buy the k&n?
GRANNY SHIFTIN AP1 You can use the OEM, the K+N just flows better. Which one of the main reasons to do the mod
After the air box mod ... Do I have to get it tune to get the power? Thanks
You don’t need a tune, you will of course get a little more power from a tune in conjunction.
but did you remove the lid as well?
Fredrik Solberg You have to remove the lid to perform the work. The lid does get reinstalled
Was the blue line on the graph without skunk2 header and flashpro? Was the difference all 3 mods or just the air box?
Like I said in the video. The dyno was done with all 3.
Please don't mod the intake, you are creating turbulence and decreasing airflow, those are there for a reason.
He didnt' butt dyno this mod though. He dyno'd it and it made power.
If what you say is true, then he should have LOST power.
@@googlepleaseleavemealonean6198 he changed the header and tuned with hondata flashpro, he didn't test this with just intake mod. There is a write up online which was tested properly and this mod lowered intake pressure, look it up.
