Super helpful. Can the intake arms be used with stock box or only Mugen intake?
If you want a direct replacement, Samco has a nice, smooth, (I think its made of a thick silicone, correct me if im wrong) arm that comes in black, red, and blue. I want the black one for my engine bay, but I dont wanna spend $140 on one. I might need to stop being a cheap a$$ and just do it.
Here is a link to those carbon ones. There are only 5 pages, so look through there and there are a couple people that made it fit with the airbox without the resonator on it. Also at the bottom of the first page there is a comparison of some of the intake arms.

i don't see how plastic made air box lid "soaks heat".
sure not in significant degree.
but if you feel it did good - just enjoy it

Which arms are you talking about man? I've seen arms made for mugen intakes modified to fit the OEM airbox. You will have to trim a little bit on the box fo it to fit right. S2X I believe their name is, sells the carbon mugen intake arms on here, and people got them to work their airbox. You also might have to cut off the whole resonator on the airbox to get something like that to fit. I would love to see the GoTuning Titanium arm modified to fit the airbox, that would look sweet. I dont think I would spend over $400 on one though since I rarely open my hood.

Thanks for the info on Samco but if I didn't do one of those two I would probably either just keep it stock or go with the full intake.

Here is a graph showing my stock intake before and after I gutted and insulated it. Red is before and blue is after. BTW, the gutted / insulated box was giving IAT's that were 9 degrees above ambient, and the stock box was giving IATs that were 16 degrees above ambient.

Here is the MAP curve from each. Red is the PWJDM and Blue is the gutted / insulated OEM box. There really isn't much difference, so it's clear that most of the difference in power is coming from resonance. The reason why MAP starts out low and increases to 3500 RPMs is because I intentionally restrict the throttle plate below 3K RPMs using DBW. I don't fully understand why, but I gain about 5 ft-lbs below 3K by doing this.

was wondering how it made resonance when its not running a standard pipe, like how resonance tuning happens on AEM V2s etc. nonetheless, Interesting data logging. Do you guys know where to purchase a SAMCO intake arm for the s2000? i went to the Samco website but it was kind of a PITA to locate..

great graphs gernby.
where would i buy the insulation material?
so this was attributed to the insulation of the gutted airbox?
