Whistle from Engine (Intake)
 

I did the search and nothing came up. When I get on it and get the car to about 3.8-4k it has a whistle sounds (almost like a tiny turbo or something), I know it may not be a problem but what is and and what is causing it. 07 ATX LT

Normal...

do you have the manifold swap. Mine does it and i think it is cool sounding. if you do have the manifold swap its just the intake sucking in air

if u have a dry aftermarket intake it will do that also

My car sounds supercharged and its just the 2.4...I know the sound comes from the engine just like the pistons loving and stuff but I think it's kinda strange.

nope pure stock no swap..just picked it up on the 6th.

might be a leak some where in the air box. but i would worry to much about it.

what kind of car is it?
