Not sure which 2003 GMC Envoy Cold Air Intakes are right for you? We have over 18563 customer reviews, with an average rating of 4.5, to help you find exactly what you're looking for. Here's what some of our customers have said:
"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.
