"The PowerAid Throttle Body Spacer was a breeze to install, taking approximately 20 minutes for this rookie to complete. The spacer does not create a whistle, as I originally expected, which is also a plus! In addition to the AirAid intake I installed a s well, I have seen an extreme increase in power; however, no increase in fuel mileage. Overall, this is a great product!" —Brandon B from Auburn, PA bought an Airaid PowerAid Throttle Body Spacer for a 2012 Chevy Silverado, 2500HD, 6.0L V8.

"This has helped my gas mileage as long as I stay out of it. The whistle is really not that noticeable unless u have the windows downs and stereo off. This was an in addition to product that I added to my volant full system cold air intake with the drop down scoop and really it has helped me push into the mid 19's for mpg's. My truck is a 08 Silverado Z71 4X4 crew cab so overall mileage increase is great. So simple to instal 4 bolts & 1 clamp less than 5 mins" —Nicholas R from Shalimar, FL bought an Airaid PowerAid Throttle Body Spacer for a 2012 Chevy Silverado.
