Airaid PowerAid Throttle Body Spacer

Reviewed By jeffrey w (Hixson, TN) Reviewed for a 2001 GMC Sierra —1/27/2011 5:19 PM

I was able to install this in about an hour. I have a lot more power but no improvement in MPG. Overall, a great product.

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.

Worth it

Reviewed By Jordan D (Hudson, NC) Reviewed for a 2004 GMC Sierra —6/14/2018 8:06 PM

It took a little bit to install it. The hose coming off the water pump got in the way a bit so it's a tight fit. You might need an extra set of hands. I could definitely tell a difference in responsiveness. Didn't really change the mpg's. But it did what I wanted it to. Definitely worth the 80 bucks.
