Popular with Jeep Wrangler lovers the world over, most drivers have no idea what throttle body spacers actually do. This Jeep Wrangler part, which is placed between the air filter and the intake manifold, increases the amount of air that is delivered to the engine. The more air there is, the more effective the combustion process. Many off-roading enthusiasts report an increase in oomph and fuel efficiency immediately after they install their JK throttle body spacers. Additional power also results in less downshifting and a more comfortable overall ride. We offer an extensive selection of Jeep Wrangler JK throttle body spacers and accessories. Replacing worn ignition components and a Jeep Wrangler performance tuner is another great way to increase fuel efficiency and power in your Wrangler.
