"I added the K&N Aircharger to my 2007 GMC Sierra with 4.8L V8, to help with it's slug like performance. The difference was impressive. So I added the DiabloSport Predator perfomance tune and the Magnaflo performance exhaust, and now my Sierra is a real contender, and sounds awesome. Great products." —Bill E from Cedar Park, TX bought a K&N 63 Series AirCharger High-Flow Intake Kit for a 2006 Cadillac CTS.
