Tegiwa Thermal Throttle Body Gasket for Tegiwa 70mm Throttle Body K-Series

TEGIWA Thermal Gasket. This gasket helps reduce intake air temps by removing the direct connection of the intake manifold to the throttle body. By placing this thermal shield between the intake manifold and the throttle body, you will help reduce the amount of heat soak the throttle body normally absorbs from the inlet manifold resulting in an increase in power. Made from PTFE - the ultimate thermo-plastic and manufactured in the UK using the latest water-cutting technology. This will only fit the Tegiwa 70mm billet throttle body for K-Series which can be bought here. Being plastic it can easily be ported to a bigger diameter using a die-grinder.
