"This was worth the money. My 5.3 V8 engine roars like a lion when ever I put the pedal to the metal. Just like what others say the install directions suck. But you will be able to figure it all out with common sense. If you have the same truck I have you will need to drill or somehow cut out a 5/8" hole for the filter housing. Gained about 3-4 mpg and more hp! Love it!!!!" —Kawam E from Indianapolis, IN bought a K&N 63 Series AirCharger High-Flow Intake Kit for a 2011 GMC Sierra.

I can definitely feel a slight difference in power, better throttle response, at least +3mpg, and the whistle from the TBS kind of sounds like I have a turbo. Great product. I am very satisfied." —Kody D from Harvey, LA bought an Airaid Intake System for a 2011 GMC Sierra.
