Have you seen the MMR piece? A straight tube, but a specific diameter and length. The C&L? A short tube with varying diameter.

I get what your saying, but there is quite a lot of R&D that goes into quality parts, and the prices reflect that. I also would never buy the small gain a cai gives for 300, however I got in on the AM preorder and paid much less, so I went for it.

One more thing, along the lines of your posts in the no muffler thread you started, I really personally think you would be happier with the sound of a cai and stock exhaust rather than, as you say, getting something that really doesn't give much improvement for nearly 500. When I put my stock air box back on to take my car in for service, I noticed how tinny the corsa system really sounds. But put the cai back on everything changes. Even my brother commented on it when I let him borrow the car. Now, he had a ws6 trans am with a borla exhaust at one time so I think his opinion is valid. What he said was 1: sounds like a v8 and 2: you can't help but put your foot in it so you can hear that sound. Corsas plus cai, I mean.

Hope this helps.

or you could be smart and look for a used one on ebay.
i found a perfectly good Airaid CAI on ebay, a little dirty but works well, and after some cleaning looks like new.
and it was only $90.

I do appreciate the answers though from most everyone else, seeing as Id rather learn why it wouldn't work then spend cash and realize there's an easier way about it out there.

so you're thanking them for giving you non-tech answers as well.

here's the tech part:
you could make your own CAI. some of the CAI out there are made from plastic and rubber.
but the hard part is making it fit, and the MAF housing and the sensor enclosure will be the hardest part.
sure you could make anything yourself. but is it worth the trouble.
for instance, using a GT500 eaton SC on a GT. its doable, but not worth the trouble and end result.
this is a microcosm of that example.

so let us know how your fabrication of the CAI goes. good luck. you're gonna need it.

There's already MAFS adapters on the market, I spent a whole 5 minutes searching to figure that out, so for just $30 I can see if all my R&D is done for me. If it doesnt than I'm no worse off than I am at this moment.
