          No noticeable difference in performance. Zero.

          I tested it with acceleration, gas mileage, uphill pushes, you name it and didn’t see a difference than the control test without it.. glad I got it on super sale or I would be returning it. Maybe a bigger one would make the difference. Super easy to install btw.

          Fun add on

          Fun add on, if you're adding an intake why not add this too. Hard to tell if you really get a performance gain from this but after adding this AND the AFE Momentum GT Intake the Jeep is NOTICABLY more responsive and WAY more fun to drive. I will say adding this spacer makes the intake a lot more difficult to fit as it is VERY tight. Over all I actually like the whole setup so I'm giving it a 5 for fun.

          Easy Install

          Seems to be some performance gain but hard to tell as I installed a new cat back exhaust at the same time.

          Easy install

          Performance gain from Throttle body spacers is always a debated topic. This is my first TBS, but I figured any minor performance increase is worth this small price. I did notice a small preformance increase, and minor MPG increase. It's hard to truly guage how much it increased, it was small but definitely notocable. This throttle body spacer is a great design, and is a very easy install. I'd recommend this TBS.
