Improved Throttle Response

Reviewed By floyd H (CLARKSVILLE, TN) Reviewed for a 2013 GMC Sierra —6/28/2018 5:58 AM

I installed this at 38,000 miles on my 2013 GMC Sierra 1500 Crew Cab 4x4 with the 5.3 Liter. I can't say the fuel mileage is better in town, seems to be little or no change but on the highway, I am getting approximately 1 to 1.5 MPG more. I can say with 100% certainty that the Throttle response has improved. I can only attribute this to the increase of air flow into the combustion chamber.

2013 GMC Sierra 1500 5.3L V8

Reviewed By Weston E (GAINESVILLE, GA) Reviewed for a 2013 GMC Sierra —2/25/2014 3:00 AM

Don't really feel much of a change at all. Installation was a breeze, 15 minutes maybe. My k&n high flow CAI already gave it the power before getting this and I would've been able to tell if any power change were there but didn't really. I don't know where they got that it gives up to 50 ft-lbs of low end torque. The whistle gets a little annoying but makes it sound almost like it has a turbo. For what it's worth, i wouldn't buy it again. But it's ok I guess.
