Rough Country’s new Throttle Body Spacer helps you get the most out of your Jeep YJ, TJ or XJ. Engineered with a Spiraling Helix design, our Durable, aluminum spacer forces incoming air into a high velocity vortex that aids in a more powerful and efficient fuel combustion process. This process offers improved torque performance and increased fuel economy. Best of all, this modification is easy to install using a 100% bolt-on installation process that can be attached in no time!
