"It was really easy to install, and this is coming from someone who doesn't even do their own oil change. It wasn't as loud as I would have hoped cuz of the factory resonator box but being a machinist by trade I made an attachment, which removes the resonator box and connects right to the throttle body and now I get the sound I was looking for.
The power is definitely there and my MPG's have improved (as long as you don't tromp on it much). I use to roll around getting 15 mpg city and 17-18 mpg highway, now I'm getting 17-18 mpg city and 19-20.5 mpg highway!
I definitely recommend this product for someone who doesn't want to spend 3 bills for the K&N" —Brian C from Fall River, MA bought an Airaid Intake System for a 2003 GMC Envoy.
