Can't remeber the name. But it's a STOCK part that should be located under the hood somewhere near the ignition.
It is alternator whine.
Trans may have a vaccum leak???

Go ask any stereo shop about it or call Crutchfield and ask them. It happens when a stereo component recieves interference from anther electrical component. It can come through rca cables, from a head unit, or amp.
I have seen it a few times and I'm trying to help you out. One that sticks out in my mind is the guy that had some kind of cheap ass equilizer in his truck that was picking up alternator noise. It did the same thing as you described. You could hear a supercharger-like whine come through his speakers when he had his stereo on. The noise would increase as rpm's increased. You could rev it up and the whine would raise and lower with the rpm's.
You need to try to rewire your system and see if that solves your problem.
EDIT: I'm saying that your head unit (CD player) is letting the interference come through into your speakers, not that your alt is making noise itself. If it was the alt making the noise, you'd be able to hear it better when you raised your hood and it wouldn't be coming through your speakers at all---all the noise would be coming from under the hood. Hope this helps bro. :beer:

That is what made me think about the alternator whine, since you said it is coming through your speakers. It could also be your ignition causing the interference.
I had this is the 99 cobra after installing an aftermarket stereo. Do you have the mach 460 system? I had an adapter that i got for the aftermarket headunit to connect all the amplifiers and speakers so i didn't have to rewire everything. On the adapter were some dials and i just simply had them turned up too high. Pulled the head unit, turned the dials down, and it went away.

Yea, I have the mach460. I also have a "interferance adapter" from crutchfield that reconnects everything too, but there's no dials on it. I havn't had the time at all to tear anything out because of school and work and such, but this weekend I'm going to go through every wire in my car..
This thread is getting long! Did we already illiminate the intake?(CAI, throttle body, plenum) Is it an air noise or a electrical whine? Is it when your rev your engine, certain rpms, hear it through your speakers?-Shane
Augh, bet you have a custom radio also. Seen several replys for this solution. You can try regrounding the ground wire off the radio. Make sure all paint is removed. One of the little cheap boxes might kill the noise. If all else fails call a radio shop and ask them since they are usually the stereo experts-Shane
