So i got the CAI this morning. Havne't installed it yet cuz i have no time.. Question for the mechanics out there... my friend has the same car as i do and rather than buying a $300 CAI (budget) he bought a K&N filter to replace the stock and took out the resonator. From what he told me, he said he can hear the turbo spool and bov alot more than he could before. I haven't heard it yet tho. Is he talking out of his a**? or is he correct?
