Skunk2 Racing Composite Intake Manifold Plenum Spacers

Skunk2 Racing composite intake manifold plenum spacers are dyno proven and road tested to outperform all other intake manifold plenum spacers. They feature several improvements, including a thicker design that increases plenum volume, lowers intake temperatures, and allows the engine's front cylinders to breathe more efficiently. All of this results in gains as high as 10 hp, increased throttle response, and a fuel efficiency increase of more than 2 mpg.

Skunk2 plenum spacers are constructed from an aerospace thermo-polymer composite that offers superior thermal insulation characteristics when compared to aluminum spacers or other heat-insulating gasket materials. Each spacer's perimeter is injected sealed for tight fitment, eliminating the OEM gasket. They are easy to install and come packaged with all necessary hardware, including the components needed to bypass the throttle body's water lines.
