Throttle body spacer

Reviewed By Matthew T (Decatur, IL) Reviewed for a 2007 GMC Sierra —3/21/2011 8:24 PM

I bought this throttle body spacer for my 2007 GMC Sierra SLE Classic hoping to get a few more mpg's. I have the 77 series K&N cold air intake already installed. I have a leveling kit, Y'ed 50 series flowmasters, but everything else is stock including tires. After installation and driving around for awhile, I have noticed better throttle response and about 1 or 2 miles per gallon better in town (15-17) and maybe 2 or 3 better on the highway (19-20). The 50 series flowmasters cover up most of the whistle, but honestly I like the sound of it.

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.
