Pretty sure this isn't normal.. anyone know what could be the cause of this? Doesn't matter how far I've driven before turning the car off, it will always make the whooshing sound.

As I lean in closer to the engine, it's quite audible that it's coming from the air intake. First, it's a slight hiss and then the rush of air coming out.

What could be the problem? Started doing this ever since I installed my supercharger along with the warm air intake. Other people with the same kit as me does not have this sound.

I might be wrong, but that sounds more like vacuum.

Ah, well you might be right about that... I never thought about it that way. If that is the case..all should be well then, right?

vacuum leaks can be even worse, as many vehicle systems rely on vacuum pressure to function. like the brake booster.
