S2000 INTAKE Versus OEM Air Box w’ mod- DYNO TEST

This is a 2005 S2000, 130k Miles, Stock header, After market exhaust.
We tested the Comptech Intake that was installed versus an OEM Intake with the AirBox mod. These tests were done back to back within 30 minutes of each other.
This S2000 will be on another video we call 'Silver Dancer' and will be sale after full maintenance and re conditioning is performed.

Life cycle of a Honda owner: Buy Honda, immediately buy aftermarket filter on a stick, throw away stock airbox. Eventually regret buying aftermarket filter on a stick, overpay to replace filter on a stick with a stock airbox from someone that wasn't stupid enough to throw it away. The end.

@ Tom Ice, brrr its cold out here since october 17 after sunset. I'd rather soak up the heat to warm the heater core in a hurry otherwise listening to Cheryl Crow telling me how she wants to soak up the sun ..get your vitamin D from it 10 minutes a day

[@scottyb226]

my understanding is that Honda has always relied heavily on tuning with certain orders of resonance to provide a passive supercharging effect at higher RPM, which is why their OEM airboxes are tough to improve on. great info here on how to keep us from tossing money down the drain.

[@hkhvr13]

I did the airbox mod because of you. Can’t wait to watch this video till the end and find out

After owning my ‘01 for about a year I threw a K&N FIPK on it. Maybe 6 months later saw your video on the air box mod. Sold the FIPK and went with the mod + K&N filter. Glad to see the numbers support that decision. Thanks for the info.

Love it guys. Love you do all in the videos for us in the audience after a long days work. Hoping you get rewarded financially, psychologically, and emotionally. What I’ve learned from your channel is if you are doing mods to a Honda basically do headers, exhaust, tune - is that correct or am I missing something?

[@thepassionofthegoose5472]

I've left the factory box on my 08 CR Delete since new. They work better than any nonsense in the aftermarket, and this run proves it.

[@518135]

Just did a bunch of testing last week on my f22 with stock header and airbox with the mod and two 3” air ducts from front bumper into the airbox. It made 231 wheel. Picked up 5 whp going back to stock airbox with the air ducts. Also using the stock air filter. S2000 love the stock airbox and header. Pretty much everything is worthless unless you throw boost at it.

[@TonyAutoWerks]

High flow cat or test pipe and a tune makes a decent gain for the money. But yeah anything else is chasing single digit hp if you’re lucky it seems

[@robertjordan9075]

Love the testing info. Thanks my friend.👍🏽👍🏽👍🏽

[@64018]

THANK YOU - I kept my airbox mod thanks to you!

[@JBaek24]

The stock box has an air inlet, and with that hood open and fan blowing at it it’s getting direct air feed. So it’s bound to make more power than a CT intake which doesn’t take advantage of the dyno run with the hood open. Imo it should’ve been tested with the hood closed to mimic exactly what it’ll be like on the street when you actually drive the car. Also, to be more fair.

[@LHTPerformance]

I meant to do that. Thanks.

[@dhwin5709]

Agreed!

[@dsmubz]

That's awesome, that's why I left the stock air box on my c7 z06, it's not a restriction and it's getting nice cold air from the fender, no need for 5 inch intake pipes with big filters exposed to all the engine bay heat.

[@LHTPerformance]

On the Zo6, typically the intakes are a larger diameter and lean out the factory mixture. You get a pretty bug gain in power and then the ecu trims the fuel back to the factory AF. Been there and done that. Lol. The intakes on the C6Z do work well.

[@oldheadneverlacking7010]

Love it, been running the airbox mod ever since seeing you guys first video on it.

[@markw8139]

Resonator does do something. It's designed to smooth out pulses coming back from the exhaust valves at each piston stroke allowing better flow. Reason why a lot of after market fancy tubes and pod filters actually loose power

[@alienweed6396]

On my del sol(stolen last montth) i had most mods on suspension. Only power train mods i had was an aftermarket header, lightweight flywheel, stage 2 clutch, and a duct that ran from under the stock filter box to the front bumper with a baby velocity stack at the end but still inside the bumper in hopes of not hydrolocking if it rained. I gotta say that was some low cost power and acceleration unlocked. I had nothing out the dig and it topped out at 120mph sure, but that little power off a dseries was much more accessible. Honda knows what its doing just follow their drift

[@coffeemonstar2]

Great video. Maybe adding a snorkel will be interesting.

[@andreask664]

Congrats for your videos!! Also I'd like to see the difference of these two + aem v2 Cai (because of the place of the filter), on the road with 100-150-200 km/h for example.. Keep up with your videos!!

[@Meister-CJ]

I've had the AEM V2 for almost a decade, never dyno tested but Might Car Mods did on one of their S2k's and there is a difference. kzbin.info/www/bejne/rqixpZ2BicRkmaM Also hello from Australia 👋

[@RingerRacing]

do the test bro

[@I_know_what_im_talking_about]

Heat soak and slower throttle response aside, the AEM V2 CAI makes good top end power and sounds amazingly deep and VTEC crack is LOUD. I had one on an 05 S2k. Made the most power during an s2k dyno day once. 💪🏻🤷🏻‍♂️

[@mannyrosado9887]

Great work! I'm surprised.

[@bwmcdonald96]

This is awesome!

[@BlueRice]

yeah. i stated few times in the past that honda develop their intake and their exhaust to get maximum performance from factory. other brand cars like Nissan i notice you could get more power from after market intake or exhaust.

[@eddieh9857]

sounds like very nice engine healthy!

[@joshk4050]

[@weksol8052]

I’d be interested in see the CT foam filter replaced with a higher flowing k&n unit that would be interesting to see. But either way, solid video.

[@dhwin5709]

I actually run the CT intake with a AFE filter instead. I do not have any comparisons. But the AFE flow rate is greater than the foam filter based on what is stated..

[@SergioBlair]

Stock air intake is always the best in NA cars. Thanks for probe it, great video.

[@joshwatton9335]

On an S2K yes. On a JDM Type R DC5 and a Euro Civic Type R EP3/FN2, the stock air boxes are shit.

[@BigSpoonWill]

Will be doing that next!

[@DaveJustDave]

Would like to see 4 tests.. stock airbox stock filter, stock airbox + K&N, modded airbox + stock filter, modded airbox + K&N. would also love to see results with all the various cooling plates and intake snorkels that work with the factory airbox. I've been contemplating doing the airbox mod + resonator block off with a snorkel, and then trimming a hole in the OEM plate that blocks off the radiator so it actually feeds cold air to the airbox.

[@LHTPerformance]

If someone wants to pay for it. Lol. This video will most likely not cover 1/2 hour dyno time. Lol. This channel doesn’t make enough money to do the kind of stuff I’d like.

i had a CAI when on the track in heavy rainfall the moisture got in there the car ran like crap. I have put another K24 engine in, 74mm throttle body, RBC intake 3" exhaust, PLM headers, Injen SRI with heatshield, KproV3 - 174kw at the hub EP3,

[@mauricios2kf20c]

Thank you friend, you are god

[@t.j2881]

I'd like to see how the stock air box stacks up against a custom cold air intake. 3.5" or 4" aluminum tube, velocity stack and a large diesel style cone filter, something with lots of surface area.

[@alejandroochoa3541]

Considering Aluminum heat soaks alot more than the plastic used in the oem one, and a larger diameter doesn’t necessarily mean more volume and in some cases in NA angines it makes the intake air flow slower i’m not sure the setup you described would be efficient

[@94fdjk31]

I have a Japan made "Top fuel power chamber" carbon intake on my ap2. I think it would be comparable to the factory modded box as the filter and fresh air duct is in the same location. The advantage of the power chamber intake may be that its filter is larger and the carbon fiber housing has a smooth flow all the way through and is wider and tapers down like a velocity stack at the throttle body. In the comparison made in this video I'm wondering with the hood closed, would the stock airbox have gotten the same cool air vs the hood being up??

[@NickEnglishPhotography1]

This would be even more interesting with the bonnet closed

[@user-on3sk3xo6o]

Wee need video like this in s2000 community.. also s2000 is very hard to find hp so please make more video about intakes and mods also try a snorkel. And please with the hood close 😛😛😛😛🏁🏁🏁

[@kyleklassen3660]

It seems like I take and exhaust mods are just completely unnecessary unless you’ve put a turbo or super charger on it. The factory stuff does not choke the motor at all when it is naturally aspirated.

[@rolandotillit2867]

How about a valve clearance dyno test. Tight, dead on, and slightly loose.

[@Azspeedin]

Silver Dancer better not be a weird grandma video..

[@LHTPerformance]

🤣🤣🤣🤣

[@bvward]

I'll put the kettle on...

[@africankat1]

now try a long aem style cai with velocity stack air filter inside bumper...that tends to perform best...im open to changing my mind if im wrong

[@robertalicea5585]

What about leaving stock airbox but remove lower resonator and add velocity stack and filter down there did that on my 9th gen accord V6 it pulls harder with it when it rains I just put top filter on and when it's not raining I remove top filter

[@geoffrohrer6223]

You switched filters correct? I wonder how restrictive (or better filtering) the other setup was compared to K&N. That could be where the majority of the gap came from.

[@LHTPerformance]

The stock air box had the K+N filter with the air box mod. The intake was just as supplied on the car.

[@liny2sd]

Thank you but, what about a not modded stick air box? Completely stock, which is what I have and I am getting ready for my first track days.

[@tomvanveen2043]

Now iam wondering what kind of results you guys will see with a snorkel on the stock intake box 🤔.

[@camlobesvtec]

It's hard to beat those stock Honda air boxes.

[@andersw1152]

Interesting test but it should have been done with hood closed and maybe one more run on the CT box. That open hood favors the OEM airbox a lot more.

[@LHTPerformance]

We actually decided to more intake testing. Including hood down and heat soak testing.

[@dhwin5709]

Agreed!

[@kalmtraveler]

not too much of a surprise there - I remember seeing dyno comparison charts back in the early 2000's. As far as I remember the AEM V2 intake was the only one that reliably made any gains over the stock airbox + high flow filter. It didn't increase peak at all but gave a small consistent bump in torque (and thus HP) between about 2500 rpm and 6000 or so if my memory is correct.

[@LHTPerformance]

Most tests are done when someone is benefiting from the results.

[@kalmtraveler]

@@LHTPerformance that's true - just meant that I don't remember seeing any dyno charts showing overall gains over that stock airbox - especially peak HP. Folks forget how tweaked the S2000 was right from the factory.

[@LHTPerformance]

@@kalmtraveler No one made money selling the airbox that comes already in the car. The magazines made money on advertising, if the big manufacturers spend Money advertising, the products need to make power.

[@kalmtraveler]

@@LHTPerformance agreed - wasn't disagreeing with you at all John. Highlighting just how good Honda's engineering was - all those aftermarket companies tried and failed to outdo the factory airbox.

[@RingerRacing]

that AEM v2 with the long tube did make midrange tq tuned on the dyno, the test wasnt from a magazine in this situation

[@user-on3sk3xo6o]

Can you make a video next time air box mod lht with the lid off vs stock air box booth with k&n on a stock car or mods but without a tune???👏👏👏

[@solidhatch]

[@WEILMAN_11]

I think the K&N filter had something to do with the hp gain, the stock air filter would be a different story.

[@RingerRacing]

doubt it

[@RRR_Motorsports]

Lies, filter would do nothing for power

[@jk_isf]

Hello John would you recommend a 5.0 final drive on an rsx?

[@dpgarage4501]

What are the plans with this s2000, John?

[@ncrx1]

I think the main reason being most of these off the shelf intakes actually end up with tubing diameter that is too small. Try making a custom 3.5" intake pipe with a filter on the end and testing that against the airbox mod.

[@t.j2881]

100% agree. I'd like to see a 3.5" or 4" intake tube with a matching velocity stack, also a big diesel style cone filter with lots of surface area

[@dsmubz]

If the intake side is not being restricted it wouldn't make any gains, probably would loose intake velocity.

[@ncrx1]

@@dsmubz have you tested this? i did back to back, 3.5 made gains on the k&n everywhere from 5000 rpms up. Had to add fuel to my tune.

[@dsmubz]

@@ncrx1 not on an s2000, with other cars even turbo cars I made no significant power or torque unless the filter,diameter of the pipe was a restriction, on my 2jz 300zx the small k&n air filter became a restriction after 600 rwhp, on my c7 z06 factory box with bigger air filter is good for 800 rwhp. Unless the filter, piping diameter or throttle are a restriction I don't think you will see any gains.

[@ncrx1]

@@dsmubz the oem intake on an s2000 has a 3.75 OD flange on the oem filter, this tapers down to roughly 2.75od at the TB. The kn intake as an example is 2.75 OD from filter to TB. Yes maybe on those engines it didnt make a difference, but it does in the case of the s2000. There is a benefit jumping up to 3.5OD with supporting 70mm exhaust, 70mm cat or test pipe, and header. if you're on the stock cat/exhaust then none of that matters.

[@sp-xx8ty]

On my ap1 i had a 3 inch cold air that went all the way to the front bumper like the civics. Made more power then all the guys at the s2k meets until vortec came out with their superchargers. Sold mine in 2008 to buy the house I just sold and made 250k on lol.

[@andreasnikou7053]

I also did the airbox mod because of you guys, later i changed to k&n fipk cold air intake and i am 100% sure the car is faster and also more respnsive. Its the only mod i really noticed the difference and i will never regret doing it or going back to stock air box. You should really test the kn fipk is one of the most famous choices. Ps: Even with air box mod at very hot days in the summer stack in traffic tha car would start jumping and difficult to accelerate (ap1 kangarooing), with the fipk never happened even once.. problem solved! Stock air box 👎 too much heat soak

[@LHTPerformance]

That’s the beauti of the design of the stock box. Heat soak is something that hurts most intakes.

The 2000-2005 require more than just a plug in flash to tune. As you can see this is a strong example already.

[@victorwilburn3498]

@@LHTPerformance I wondered since mine was a '08 and I thought Honda made changes from 2006 and up. That car is the strongest "stock" S2k I have ever seen. Exactly why I imagined it fully uncorked. If I ever get another S2k I will find a high mileage motor and convert it to a 2.4 liter stroker (Inline Pro) and have you work your magic on the tune/exhaust. Just prefer NA cars and the one 2.4 liter stroker I have been in was a revelation, massive torque, top end HP and rev'd like a motorcycle. Glorious engine the F22.
