All in all I am impressed. My car drives alot 'smoother' The throttle response is noticeable and most of all the sound is great. I did not in anyway whatsoever want my car to sound like a ricer. The engine starts roaring after 3000 RPM. If your looking for a cheap upgrade with alot of kick the AEM CAI is the way to go.

You can feel the Torque
