Skunk2*s revised Nissan/Infiniti VQ35 Composite Intake Plenum Spacer V2.0 is dyno proven and road tested to outperform all other intake manifold plenum spacers. Skunk2*s Intake Plenum Spacer V2.0 features a number of 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 2mpg. Unlike competitors* spacers, Skunk2*s Intake Plenum Spacer V2.0 is constructed from an aerospace thermo-polymer composite that offers superior thermal insulation characteristics when compared to aluminum spacers or other heat-insulating gasket materials.
