DESCRIPTION

Do you know what your intake manifold sits on?...a superheated boxer engine. If you don't know already, the cooler your intake air is the more HP your car will achieve. We present you the answer to this age old problem, raising the intake manifold off the engine with GrimmSpeed's Phenolic Intake Manifold/TGV to Engine Thermal Spacer. Phenolic spacers have been used for years by many other specialized automotive companies, but this is new technology to the Subaru world.

WHY?

While the intake air is within the intake manifold it picks up a lot of heat from the aluminum intake manifold. This added heat reduces air density thus reducing engine power capabilities. Phenolic Spacers are able to withstand 500+ degrees F. Subaru engines run at the hotter end of operation around 200 degrees F, so the Phenolic Spacer is well within its max running temperature. GrimmSpeed has tested that it is also safe to run race fuel, E85 and methanol with the Phenolic Spacers.

FEATURES:

  • Greatly reduces the transfer of heat from engine to intake manifold thus reducing heat soak.

  • One-of-a-kind true Phenolic material, not cutting board material like others.

  • The cooler your intake temperature is, the denser the air is which leads to more power.

  • For every 5 degree reduction in air temperature, increases power by 1%.

  • Cooler and denser intake air, increases the amount of air that can be mixed with fuel thus increasing efficiency.

  • Direct bolt-on

  • USA made
