"This product is an easy install and makes your motor sound like a monster at high rpm's. I haven't put it to the highway mpg test but around town I haven't noticed an increase. Slight increase of power over entire rpm range. I also installed a throttle body spacer with my intake." —Austin L from Williston, ND bought an aFe Cold Air Intakes for a 2009 GMC Sierra.

"I was very happy with the looks and quality of this kit.Everything went in place very easily until it was time to put the main elbow to the throttle body connection. It would not fit without mods to the fan shroud and the elbow.I cut a small notch out of the fan shroud and cut 1 inch off the elbow then it fit quite nicely.The breather hose was very tight going over the breather tube on the engine,one size larger diameter would be a help there.Everything else fit very nicely and looks great.I havent run my truck enough to notice a difference in mpg but it sure cant hurt." —Trevor P from Washburn, ME bought a Spectre Cold Air Intake for a 2009 GMC Sierra.
