"This thing was on sale over the holidays and I did my research because I was interested in the k&n but couldn't see myself paying almost 100 dollars more for something with all the same specs basically. I went with the Airaid and could not be happier. Love this thing" —Craig P from Goldsboro, NC bought an Airaid Intake System for a 2005 Chevy Trailblazer.
"Very pleased all the way around. It is a bit loud above 2500 rpm but sounds great! Couldn't be happier" —William G from Dallas, OR bought a K&N 77 Series Metal Intake Kit for a 2005 Chevy Trailblazer, 4.2L 6-cyl. engine.
"Looks great, more power, however I have not had the opportunity to check mileage. The only thing I didn't like was having to cut my own 1 1/4" hole in the intake." —Frank W from Chesterfield, MI bought a K&N 77 Series Metal Intake Kit for a 2005 Chevy Trailblazer.
"Really like this intake. Could tell a difference right away. Better throttle response. Read that TBS could not be used with this CAI but installed one anyway. Man what a difference. Maybe no mpg gain but definite torqe gain. Would recommend this CAI to anyone in need." —Todd M from Pikeville, NC bought a Volant Cold Air Intakes for a 2005 Chevy Trailblazer.
"This was an easy install, and goes well with my throttle spacer. I noticed faster throttle response. This intake isn't that loud, because you retain the smaller air box that connects to the throttle body, but you do hear a little bit of that nice open intake sound." —Gregory F from Cheshire, CT bought an Airaid Intake System for a 2005 Chevy Trailblazer, 4.2L 6-cyl. engine.
"The installation process would have been much easier, had all of the necessary parts been shipped. Having to purchase parts from a local hardware store that were missing from the package put a damper on the entire project. Having said that, I can definitely notice a difference in performance. Engine RPMs are lower, gas mileage has seemed to improve and the motor has a subtle, but notably deeper sound." —Clay L from Laurinburg, NC bought a Volant Cold Air Intakes for a 2005 Chevy Trailblazer, 4.2L 6-cyl. engine.
"easy install. great power and the extra mpg's awesome!! i will now have one of these on every vehicle i buy from now on!! great job on the fast delivery!!" —Michael M from Midlothian, IL bought a K&N 77 Series Metal Intake Kit for a 2005 Chevy Trailblazer, 4.2L 6-cyl. engine.
"This intake was put on a 2005 Chevy Trailblazer and made a noticeable difference right away. It was very easy to install." —Shane H from Savannah, GA bought a K&N 77 Series Metal Intake Kit for a 2005 Chevy Trailblazer, 4.2L 6-cyl. engine.
