I have had an intake in my Cavalier for a few years now and like the HP increase. After the install on the Trailblazer I instantly felt the increase in HP and the sound from the engine compartment wasn't that loud at all. I have noticed about a 1-2 mpg increase for the tank of gas that i ran after the install so that's a bonus for me since I run about 250 miles a week commuting to work and back. Installation wasn't that hard, the directions that are provided are straight forward and easy to understand. The K&N uses existing bolts and holes so swapping back to stock is a breeze with the exception of cutting the air return hose. I had an extra hose from a previous repair so i'm not concerned about that. Overall I love my intake and would recommend it to anyone.
