I've got the same problem with my Airaid CAI. Its a very annoying whistle/squeal. When I took it into the dealer and drove the tech around, I had the sound all day long. His advice; re-install the stock parts or turn up the radio. I'm seriously thinking about taking it off. The 10-15 HP gain I got isn't worth it and I feel it was a waste of money.
