Hey guys,

Now I know that sucking air in is what the CAI is supposed to do.

However, it is now audible in the cabin, hardtop/ soft top on or off. In the engine bay it is heard at the firewall (where the CAI pokes through) and at the intake manifold.

The noise continues for a second or two after I turn the engine off.

I can not recall hearing this prior to the battery going dead the other week.

Am I being paranoid to worry about this sound?

Matt

I don't think thats the CAI somehow.
aircon?
some other air pressure?
water pressure?

Mine does that too...kinda like the car doing a great big sigh at not being able to drive anymore

Yep mine does the same. It sounds like water flowing through a pipe at idle, with a faint hissing noise. Nothing to worry about in my opinion.

mine also does the exact same thing in fact i have often turned off my cd player just to listen to it and the end of a drive, i love the sound never ever thought it was something to worry about!!!!

Mine does the exact same thing and has so from the first turn over from installing an induction system. I love that noise, sort of like the car saying good night.

Put the little muffler back on!
