I get a screeching noise everytime the car shifts, it's an A4. Comes from the front. Is it my CAI or belt. I was thinking the belt. It seems to be getting louder, but that may be in my head.
Anybody recommend a good belt?

 

Get a Goodyear Gatorback.

 

It's the belt. Mine does the same thing & I don't have a CAI.....yet. I can't think of a great belt off the top of my head, but the GM replacement should be just fine. Yours' probally has a glaze on it like mine & just needs to be replaced.

 

A great belt is the Gatorback. They sell them at Autozone now.

 

Look at the bottom of your water pump. If one of the bolts is shiny then get the new belt. I typically could only get it to happen in Perf. Shift mode.
