Ttop dont know shit. LMAO!
However to answer your question, get the one from cosmoracing.com and then just get the other piping to convert it to the ACTUAL cold air. I had ran the cosmoracing SRI for awhile and it made an okay difference. But when converting to a CAI, it didn't make that much of a difference other than the sound. Also, take ttops advice and run a bigger cone filter on it the 2.5" or 3" just doesn't get enough air IMO
Love ya Tom
