Tegiwa Thermal Throttle Body Gasket 70mm Honda B-Series B18

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, 70mm ported OEM, Skunk2 Pro Series etc (will not fit RBC flange). Suitable for 70MM throttle body such as Skunk2. Being plastic it can easily be ported to a bigger diameter using a die-grinder.
