Review on 🚀 High Performance K&N Cold Air Intake Kit: Increase Horsepower for 2003-2004 CHEVROLET/GMC (TrailBlazer, Envoy) 57-3048 - 50-State Legal by Quinton Wonsley

Installation was easy for anyone with a working knowledge of screwdrivers and wrenches. Very easy to follow instructions with photos of each step. It took about an hour and a half, just don't rush. The only issue I had during installation was how close the intake manifold was to the fan blades. I did some research and found that this kit is built that way and that the brackets that come with it are more than enough to keep the pipe from hitting the fan. The MPG hasn't changed much in the city due to normal driving habits, but there have been big changes on the highway. I'm seeing numbers averaging 4-5 mpg better than before the install. The power of the vehicle was also noticeable. Increases 20 hp for the price I paid for the kit is not easy to achieve. Great bang for the buck! I like both the sound and the look. I would like to say to anyone thinking of buying this set that you will not be disappointed.
