High pitched whistle when you accelerate? I found where mine was coming from.

Well that whistle was starting to drive me crazy and I set out to find it. Only took about 2 minutes. The air boot was cracked, and cracked badly. I have no idea how it could not have throw a code or made the car run rough. Anyway grabbed a new boot and slapped it in and the noise is gone. I have read a lot of others have heard this noise so I am sharing my finding.

The boot cracks on the bottom of the little tube, and is not easy to see. Its also not easy to get to the hose clamps. I had to get them with a really long extension from under the car.

I hope that was not posted already, I did not see anything about it.

Thank you for this info. I just discovered mine this past week and it is annoying. I am going to schedule the dealer to fix it since its still under warranty.

Air boot? Which part are you referring to and on what type of engine?

3.0 and it's the air boot directly under the intake. It goes like this MAF then a plastic pipe then a plastic junction then the Air Boot (rubber). Finally into the intake manifold. The Air Boot has a small rubber tube running off the side of it to the secondary air system, that’s where I had the crack, and it was so low I did not see it right away.

Sorry about the formatting.

I have a 4.4i with a slight whistling sound (no driveability issues). I'm looking for comparable parts to see if I'm having the same problem.

Number 9, that little thing shooting off it had the cracks on almost all the folds. 65K on motor and no other sign of a problem other than that @#&*^%$# noise.

Follow your intake, the air boot will be the last connection before the throttle body.

Thank you so much - this noise has been irritating me for awhile now, and I do not drive it everyday.
