Review on 🔥 Airaid Cold Air Intake System - Enhanced Horsepower, Premium Filtration - Fits 2002-2005 BUICK/CHEVROLET/GMC/ISUZU/OLDSMOBILE (Rainier, Trail Blazer, Envoy, Ascender, Bravada) - AIR-200-126-1 by Brian Diaz

I have used this system on a 2002 Chevy Trailblazer for years. I also got an Airaid throttle body seal. Together they took just over an hour to install, but having done it once I'm sure I can do it in less than 30 minutes. The results are very good. They added about 4 mpg on the freeway, and trust me, Trailblazers are known for lousy mileage, so every little helps. Throttle response is just as good, if not better than when it started. Now he has over 150,000 km. If you have mechanical skills you can install this. If you don't have one, find a friend who will offer you 12 packs of REAL Sugar Pepsi (no crap with HFCS) or 6 packs of decent beer. :) Better price than K&N and better support too. Highly recommended.
