I bought one for my Yukon a couple of years ago. It made a high pitch whistling noise that was annoying. I returned it to
www.autoanything.com for a full refund. Waste of money. I'd say the same for most intake systems as well. I learned the hard way as I've purchased K&N FIPK, Airaid wit MIT, and now the GM Performance Intake Kit. Again, waste of money.
