Thermal Inlet Gasket - Z20LEx
Thermal Inlet Gasket (TIG) for Z20LEx engines - designed to reduce heat-soak from the cylinder head to the inlet manifold. Ideal for use with any engine, but especially big power builds.
Heat management is an area that is often ignored during engine modification. The Thermal Inlet Gasket will help prevent heat from conducting from the cylinder head casting into the inlet manifold, significantly reducing heat soak.
In theory, because of the cooler and denser inlet charge, a small and immediate power increase should be evident (if you can run a little more ignition timing before pre-ignition occurs then power should rise), but their main strength will be in helping to keep temperatures under control during and after prolonged engine use.
This 4mm thick high performance composite gasket, designed for optimal heat insulation, is available for Z20LEx engines and is paper coated on both sides to aid sealing.
Note: The TIG is paper coated on each side and designed to seal between two flat surfaces. If there is any doubt about the quality of either surface a thin bead of sealant should be used on both sides (not recommended unless absolutely necessary). If the paper gaskets are damaged during strip down/rebuild, they can be replaced with a pair of OE gaskets, one to be fittd on each side of the thermal gasket.
