So I installed my CAI today. Followed the instructions to a tee and everything bolted up perfectly. I also cleaned my throttle body while the stock intake was off. Some build up but nothing out of the ordinary. Took the car for a spin and noticed, somewhere between light and medium throttle input, I can hear a slight metal on metal squeak. At WOT, all seems good. It's only off the line and at VERY specific throttle position while cruising.

Am I correct in assuming the noise is coming from the butterfly valve? Is it possible I "over cleaned" it and the hinges are the cause of the squeak? If I'm light on throttle input, there is no noise, only at normal acceleration do I here anything, and it does go away as the car picks up speed.

I'm going to give it a week and see if some carbon build up clears it up. BTW, the car runs great with no lagging issues. Thoughts?

Ive cleaned the crap out of my TB and no squeak. Are you sure it isnt more of a whistling noise? MY spectre has a light whistle at about 2K rpms then screams at WOT.

I dont think the butterfly would squeak...

I suppose it could be considered a whistle. Sort of a combo between a whistle and a squeak. I've searched a bit and some people say it's normal, others that it may be a leak.

I'd check all the connections/clamps then. Could just be a simple air leak.

My Spectre whistles at light throttle...sounds almost like a turbo or a Procharger at idle...

I double checked everything and it's snug as a bug. I thinking since the resonator came off with everything else and the air flow is more direct, the whistle is normal. More air passing through at a certain throttle position. All seems normal and the car runs great, so I'm going to leave it be. I actually kind of like the sound, just wanted to make sure it was normal. Thanks guys.
