"Easily installed in two hours with a helper. (Gopher). I havn't figured out the mileage yet but I will. I called the Chevy dealership and asked how this was with the warranty and he said as long as you don't over oil the filter. Looks a lot roomier under the hood also." —Robert Z from Westmont, IL bought a K&N 63 Series AirCharger High-Flow Intake Kit for a 2011 Chevy Avalanche, 5.3L V8.
