When i shut the car off after a drive, i hear a hissing sound. Like someone letting air out a baloon. The car runs perfectly fine, but I was just wondering if that sound is normal.

Is the sound coming from the intake?

Hrmm..I really don't know. It's just whenever I turn the car off, it hisses like air is escaping. I'll pop the hood and turn the car off and try to pin point where the sound is comming from. Does anyone elses car do it?

Like said above, might be the CAI if you have one. Mine does it all the time when I shut mine off.

That is a common sound on these cars. Do you have a boost bypass on yours? All of my friends and mine does the same thing. No cause for alarm.;)
