This thermal gasket is made from PTFE which is is a higher grade material than other thermal gasket brands.
Operating temperature range is: -200 ~ + 327°C. This thermal gasket replaces the stock intake manifold gasket which virtually eliminates heat transfer from the cylinder head to the intake manifold, Thermal Throttle Body Gasket use a High temperature thermal polymer material protects against heat soak and maximizes horsepower gains by reducing heat transfer. Also These are reusable gaskets
By doing this air intake temps are reduced which provides the engine colder air for combustion.
This is perfect for race or street use
