Throttle Body Spacer, 3.8L, 07-11 Jeep Wrangler 

The Rugged Ridge Throttle Body Spacer raises the throttle body 1/2 inch above the intake manifold. The additional space helps optimize power and performance by drawing in colder denser air. And, the large bore design allows your system to inhale a larger volume of air. It features solid aluminum construction with a slick anodized finish, and adds bolt-on performance for 3.8L engines.
