Review on πŸš€ K&N Cold Air Intake Kit (77-3037KP): High Performance Horsepower Boost for 2003-2009 Hummer H2 6.0L/6.2L V8 by Corey Harris

Revainrating 5 out of 5

Very impressive best in Filter

I noticed a slight increase in gas mileage and a significant increase in power. This filter was the finishing touch on my 2003 Hummer upgrade. I also have a dual exhaust with Flowmaster 40 series mufflers and a Superchips programmer. The filter was like a nice nod to the packaging. Also, this filter eliminated the slight wobble I had when I pressed the pedal to the floor.

Pros
  • Spare parts
Cons
  • Crumpled packaging
