Review on K&N Cold Air Intake Kit 77-3062KP: High Performance, Guaranteed Horsepower Increase for 2006-2009 CHEVROLET/GMC/ISUZU (TrailBlazer, Envoy, Ascender) by Demetrius Young

Revainrating 4 out of 5

Quick and easy performance upgrade

I've always used K&N in my cars so it's not a problem. Easy installation, only took about 45 minutes. I get about 2-3 mpg on the freeway (although the hills are virtually non-existent). As for mountain riding, you can definitely feel the power when accelerating uphill, but my mpg dropped to around 15-16mpg (08 Trailblazer).

Pros
  • EASY MAINTENANCE: No filter required to clean up to 100,000 miles
Cons
  • Zero
