      The RCM Thermal Gasket kit contains everything required to install our Phenolic Spacers to your Impreza.  

      The kit is designed to aid in the reduction of the inlet air temperature, by isolating the inlet manifold from the heat generated by the engine's cylinder heads.  

      By reducing the temperature of the inlet manifold, the temperature of the inlet charge is alos reduces.

       The density of cooler is greater than that of warm air, and a denser intake air charge contains more oxygen which results in the potential for increased power and torque.

      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 KW your car will achieve. We present you the answer to this age old problem, raising the intake manifold off the engine with GrimmSpeed'sâ„¢ new real Phenolic Intake Manifold/TGV to Engine Thermal Spacer.


      What it does:

      Greatly reduces the transer 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 powerFor every 5 degree reduction in air temperature, increases power by 1%.The cooler and denser the intake air that the engine sucks in, increases the amount of air that can be mixed with fuel thus increasing efficiency.

      How it works:

      The intake air in your engine travels through the airbox into the turbo, then into the aluminum intake manifold. The air exits the intake manifold and goes directly into the engine.

      While the intake air is within the intake manifold it picks up alot of heat from the aluminum intake manifold. This added heat reduces air density thus reducing engine power capabilities.In stock form your engine has a steel gasket between the intake manifold and engine which allows the heat from the engine to quickly transfer into the intake manifold. By replacing this steel gasket with the GrimmSpeedâ„¢ Phenolic Spacer you are greatly reducing the transfer of engine heat into the intake manifold.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. GrimmSpeedâ„¢ has tested that it is also safe to run race fuel, E85, and methanol with the Phenolic Spacers.The Phenolic Spacer will conduct 300-900 times less heat than the oem steel gasket.
