K&N 77 Series Metal Intake Kit Reviews

Better MPG and throttle response

Reviewed By David P (HUNTSVILLE, AL) Reviewed for a 2015 GMC Sierra —10/24/2016 6:09 AM

I've had this installed now for about 3 weeks. Installation was very easy and the intake looks much cleaner than the chunky factory airbox and resonator. Improved throttle response was noticeable on the first drive - the truck just seemed to get going with less throttle input. Fuel economy is up 1-2 MPG for both my commute (mix of stop and go and highway) and for highway driving. Since I tend to keep my vehicles for several years (5-7+) this will definitely pay for itself.

K&N 63 Air Charger

Reviewed By Thomas H (PUNTA GORDA, FL) Reviewed for a 2016 GMC Sierra —9/24/2016 12:27 PM

Improved acceleration, better mileage and cool sounding. Installation a hassle because 2 of the hose clamps were too small and I had to run to auto parts store to purchase correct size.
