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.

It took me about 2 hours to install but did fit very nice.I like the look of it. If you drive normal, it is still quiet but as soon as you get heavy on the pedal, you can hear the difference. I haven't noticed yet if it is helping the M.P.G.
