Product Description
The kit replaces your vehicle's restrictive factory air filter and air intake housing. K&N intake systems are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your vehicle's engine to inhale a larger volume of air than the OEM air filter assembly. More air means more usable power and acceleration throughout the engine's RPM range. The filters on these kits are washable, reusable and easy to install with tools commonly available.

2004 Avalanche 5.3 stock

First of all was the great price and fast shipping. I received in 2 days. Easy install, about 30 min. Very noticable engine roar on acceleration like you have a performance exhaust (mine is stock right now). Noticed a slightly faster pick up on a kick down acceleration. Haven't noticed any fuel mileage improvement yet, but it's hard to stay out of the throttle with the sound it makes. The easiest and quickest performance upgrade you can make.
