Review on K&N Cold Air Intake Kit for 2004-2006 Chevy/GMC/Hummer (Colorado, Canyon, H3) 3.5L L5 - High Performance, Increased Horsepower, 50-State Legal (Part Number: 57-3043) by Mike Sutherland

Check the motor in the air intake

This product is great! For anyone getting code P0171 (too bad). This is because you are not using a Mass Air Flow (MAF) sensor. I bought one from Jet Performance and no codes. I've been driving the car for 9 months with no codes. Keep in mind that a performance MAF costs about $170.

Pros
  • Everything is fine!
Cons
  • Not the best
