"After installing the throttle body extender, the power was immediate noticed. Going up familiar hills was different in that auto shifting down was less one gear and sometimes 2. This has to equate to better gas mileage. The economy indicator proved this out. Not os much on short, stop and go runs but rather on freeways where the speed was up and maintained." —Walter J from Oceanside, CA bought an Airaid PowerAid Throttle Body Spacer for a 2011 Jeep Grand Cherokee, 3.6L V6.
