airbox mod

It's been around for a long time. Aftermarket intakes will make more power and there's plenty you can do to combat heat-soak. I live in the desert, I don't get any appreciable heat-soak.

I did this mod a long time ago, sound got maybe a little bit louder, didn't notice any other difference.
But I guess the mod can't hurt anything.
With the airbox lid completely removed VTEC sounds just incredible, but I guess you will have significant heat soak issues then.
I didn't notice heat soak the one time I tried it, but it was mostly highway driving and almost freezing outside haha.

I won't do this until I see a real Before&After dyno (with just/only the airbox modification and nothing else - no tuning, other parts, etc.). I'm pretty sure Honda engineers know what they're doing, lol.

I would also add a 3" to 3 1/2" hole on the end of the air box to let more air into the box. Now if you do this you should run a hose down to the wheel well so it grabs cool air.
Here is a post I made 6 years ago about a restriction with the stock air box I found on my '06 S(all stock).

I did cut a little of the divider out, left about 1" or a little more in the bottom of the air box and added the hose on the end of the air box. That took care of the restriction that my S had.
I believe the air box opening in the front of the air box is the same for the AP1 and AP2 so there might be no restriction on a 2.0L AP1 but will have a little on the 2.2L AP2.
Like I said in my '12 post I added this gauge so I knew when to change my air filter, changed it out at 90k miles not because of any restriction but because of the age of the filter.

While the Honda engineers are "on point", they have to "tune" the car for every possible traffic scenario and possible owner / prospective buyer "oh that S2000 is just too loud" , meaning the intake.
I just want something for the track but I'm not spending $300 on a K&N or AEM intake.
Think link above keeps the same OEM filter which can likely be improved upon.

That is the exact reason it takes an army of engineers to build a car. the airbox design has to meet strong requirements (NVH, performance, size, efficiency...), not just a "make it cheap to build" one, and this goes for every component used. The days people could get more horsepower by just hacking around is gone

Deleting the transition feed completely does nothing but mess the intake chamber up !!
I modified mine by making it a longer opening and keeping all of the curve,so keeping transition too filter.+ I have a cai snorkel to grill opening,
taking it out completely may help initial throttle , but loose any transition from then on,will get bad turbulence in the air chamber,oem is not designed for that..
