I just installed my aem Intake, it sounds and runs great but I'm bot sure what the noises are about, when I shut the car down and when I shift, if makes these noises, I can't even explein,. someone said it's normal but I just want to make sure. something about the engin gasping for air, but why would it have to do that? other than that I love it...p.s. there are no engine lights coming on so that's a good thing, right?
