Airaid PowerAid Throttle Body Spacer Reviews


Works good

Reviewed By Scott J (NOKOMIS, FL) Reviewed for a 2006 Hummer H3 —1/7/2014 9:49 AM

I put the Airaid PowerAid Throttle Body Spacer on my 2006 H3 Hummer with the 5L engin. At the same time I put on the K&N Cold air intake. They both work great together. I have had it on for 2 weeks and get about 3 to 4 more mpg on the Highway. Also notice an increase in pickup when moving into passing gear. The Throttle Body Spacer makes a small whisteling sound , but not to loud. You cant hear it at all with the radio on. Some people like the sound it makes, but it really is not that noticable.

Nice Improvement to Idle!

Reviewed By Todd B (SEMINOLE, FL) Reviewed for a 2011 Chevy Camaro —8/10/2018 12:58 PM

It was extremely easy to install and after fuse pull to reset ECM, beyond perfect idle (was very good before) and noticed a solid feel and quicker response when accceleraring. Also added a ram air cold intake a week later and together...what a nice surprise!

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.
