My intake whistles which I am pretty sure is normal. It is kind of loud, sort of sounds like a blow-ou valve (vaguely). But I hear whistling from the rear of the car, sounds like air is almost leaking from the passenger side of the window. I have really no idea other than that. It only bothers me if this is a problem. I think that is sounds pretty B/A. Any thoughts?

check your vac connections... that can cause a whistle... or if you're in Northern IL, PM me, maybe we can set up something.

You may have an exhaust leak. They love to whistle, especially when you decelerate Check your passenger side exhaust piping, manifold gasket, etc.

when i put a CAI on my V6 it had a whistle unless it was in very low rpms. put the same brand on my GT and it doesn't whistle.

maybe it is your CAI because it is on the passenger side?
