"i bought this product for my 2008 chevy 5.3. a few questions during instillation but overall pretty simple. i like the look, and the sound is good too. i noticed better throttle response, a little better accelleration, and the rpms also drop faster between shifts. less lag, a little smoother. does what it says it will do. overall great product. i would recommend it. after all it is only $100, why not?" —Kale L from Clarksville, TN bought an Airaid PowerAid Throttle Body Spacer for a 2008 Chevy Silverado.
"I installed the Airaid throttle body spacer in combination with a K&N intake system on my 2008 Chevy Silverado crew cab and it sounds amazing. I have 35" tires on 20" wheels with a six inch lift so I was getting about 9-10.5 mpg. With this combo I'm averaging 12-14 mpg. There is deffinently more power across the entire RPM range. I recommend buying the combo, but don't expect a huge miracle. Every little bit helps though." —Bryan I from Carlsbad, CA bought an Airaid PowerAid Throttle Body Spacer for a 2008 Chevy Silverado, 1500, 5.3L V8.

"For the money ($100+) it is worth the buy. My fuel economy just around town went up by about 2mpg (when you are easy on the gas pedal) will get to test it out this weekend on a 140mi round trip. But throttle response is noticable and made the exhaust more throatier. I will be adding a flowmaster super 44 and an intake system but you can definately notice a difference with just this. I am pleased and would (and have) recommend this to anyone!!! My wife even noticed (without me saying anything) on the truck being more responsive and she told me (you must have bought something for it) and.... she was right..." —Jason R from Jamestown, ND bought an Airaid PowerAid Throttle Body Spacer for a 2008 Chevy Silverado.
