Phenolic Spacer for Subaru EJ20


5mm Subaru EJ20 intake manifold Phenolic Spacer

Phenolic inlet manifold gasket for your Subaru Impreza, Subaru Forester and other EJ20 engine cars acts as a barrier stopping heat transferring from the engine block through into the inlet manifold.

Stopping this heat transfer results in a cooler inlet charge temperature and in doing so increases engine power in much the same way an intercooler does, except this is able to benefit a turbo and non-turbo setup.

Subaru Impreza WRX phenolic spacer is perfect fitted item.
