I was wondering if anyone's short ram for the I4 ever makes a wierd sound when your car is on? My intake is making a really high pitched almost whistling noise. I dont know if thats normal or what....anyone?
I've noticed that this happens alot with, i think they're called vortex cone filters. My buddy had a problem like that on his del slow and i told him to drop a normal cone filter into it and the tone went down a bunch. So that is another possibility
