Rusty's Throttle Body Spacer ('91+)

The Rusty's Throttle Body Spacer is an economical way to get more horsepower and torque while also improving fuel economy. They are constructed of an advanced phenolic material that is specially formulated to reduce heat transfer compared to aluminum spacers. The Rusty's spacer raises the throttle body one inch. The spiral shape of the bore in the spacer rotates the air as it enters the intake, which promotes a better air / fuel mixture and more complete combustion. All of this results in up to 6 to 10 rear wheel horsepower, better torque, and even a 1 to 2 mpg improvement in fuel economy depending on driving habits. The Rusty's Throttle Body Spacer comes complete with gaskets, linkage spacers, mounting bolts, and complete instructions.

This spacer works with '91+ XJ, ZJ, TJ, WJ 2.5L & 4.0L Engines Only
