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 technologly. This will fit all inlet manifolds, OEM, Skunk2 etc. Suitable for OEM B16A throttle body. Being plastic it can easily be ported to a bigger diameter using a die-grinder.
