the S2000 has such a good desing, it looks good even more than 20 years later

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.

Same with my ek with the ek9 style oem intake box the air temps stay colder and more consistent thant the cone filter.

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.

These are really my favorite videos from you guys. I know it can be a pain, but I'd love to see more as you get some spare time and get parts to test. Either way, thanks for doing this!

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?

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.

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.

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

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.

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

Great work! I'm surprised.

Great video. Maybe adding a snorkel will be interesting.

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

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

sounds like very nice engine healthy!

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.

This is awesome!

Will be doing that next!

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.

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.

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.

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

2 жыл бұрын

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

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??

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.

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

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

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

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 😛😛😛😛🏁🏁🏁

@@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.

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.
