So I have been toying around with this idea and would like to get your opinions.

I had a 2002 S2000 and installed a comptech CAI on it. I loved the sound of it, but let's face it with CAI all you are "really" getting is sound and not the HP gains they claim. I would rather not fork another $300 plus for the sound. FYI..The comptech CAI was a plastic box with a carbon fiber lid.

I believe that Honda designed the S2000 air box to cut down on the acoustics. I am sure several of you have at least heard what the car sounds like with out the air box lid on. It has the CAI sound to it.

My idea - I still have the my air box from the 2002. I am thinking of cutting the top portion of the lid out and replacing it with a sheet of 0.015" carbon fiber. I am hoping that the carbon fiber will allow more groan from the intake.

Do you think it will work, or am i missing somthing? Is there another material besides carbon fiber that would work better?

I am hoping that this will give me the sound I am looking for, with a "cool" look, less heat soak, and at a reasonable price!

I would think that just by replacing the top with some other kind of material (CF in this case), you'd still not get that big of a sound difference, because you're still trapping the air the same way as the plastic lid would -- thus the air is still flowing the same way as before.

But that's just my theory, don't take it as a fact because I'm not an expert, hehe.

 

I agree... I don't think the increase in sound from the Comptech intake had much to do with the CF lid on the airbox.

I see what you are saying, but I am wondering how the Comptech CAI still produces the sound I desire. The Comptech filter is completely enclosed in a plastic box with a carbon fiber lid. The OEM air box without the lid still produces the same sound. The carbon fiber lid will be much thinner than the OEM lid and obviously will not be designed to kill any noise.

Do any of you happen to know why the stock air box has 2 chambers in it? Their is a chamber where the air filter sits and another chamber that is empty. I wondering if the wall between the 2 chambers is there to kill the noise as well.

 

yep - second chamber is for sound dampening.

if you want to make some cuts, see thread 2 and thread 3

There's a bunch more posts in the "under the hood" forum...

 

Good threads...thanks for sending them.

I am going to try altering the box. I am also going to try my idea in combination with the cutting/plugging.
