i have recently installed a injen intake. it sounds all deep and stuff but when i let off the gas really fast and when i shut the car off i can hear this WHISTLING SOUND for about 1 or 2 seconds.
Anyone else with this or tell me why this is happening?? thanks

Sorry, couldn't tell you what the whistling is, but I'm interested in that particular intake. I have a Stillen Intake myself, but was looking into a traditional CAI. Can you describe the added performance? Also, where did you get yours, and how much. AIM HIGH!!

I have ordered mine from southwest auto works for 229.00 . You can actually feel a difference in throttle response, car is a bit more peppier, also the intake looks damn pretty also the sound is deep especially in high rpm's. I'm still trying to figure out about that whistling sound though..

g-cia35,

I have a INJEN RACE DIVISION intake also. That sound you hear is also what I hear. But what like what turbonismo said its like the car taking its final breath. I was worried what that sound was also. But its pretty normal.
