Gizzmo Electronics GZM-G6041 Gizzmo Phenolic Thermal Intake Spacer-Gasket - Toyota 1U V8

The Gizzmo Thermal Gasket is a thick Phenolic inlet manifold gasket that 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.
