"Have only had the CAI kit installed for 2 weeks, but so far have found Spectre's product just as good as the others I've installed and used in the past. Very good quality & fit/finish. And with it costing much less, this one has definitely been the best bang for the buck. Installation was easy on the Yukon. 'Course you will have to put a little effort in putting on a couple rubber tubes that fit very nicely, but that's how the others were, so no surprises. Take your time to install and you shouldn't have any problems. Yukon feels a little stronger, and at or near WOT, sounds absolutely awesome and way better than the stock intake. My wife is even hooked. When we're behaving with the throttle, engine sounds normal/stock (not loud at all), and we've noticed about a 2mpg improvement on highway and around 1 mpg gain in city driving. After driving ours, my buddy just picked up the same Spectre kit for his 04 Suburban." —Claus R from Bolingbrook, IL bought a Spectre Cold Air Intake for a 2003 GMC Yukon XL, 5.3L V8.
