Randall D from Blaine, WA said, "Application 2003 Tahoe,Installation took all of about 20 minutes. I have read reviews from others saying that it is a difficult and time consuming affair...it is not. Remove 5 of the most forward inner fender liner snaps (passenger side) and the bottom of the inlet of the intake box is clearly visible. Once removed you will see how easy it is. You "Do Not" have to install it from the bottom and try and reach your hand up to tighten the hose clamps...voila!"
