Product Details

The Cosworth Thermal Guard Composite Intake Gasket is designed to aid in the reduction of inlet air temperature by isolating the intake manifold from the heat generated by the engine's cylinder head. By reducing the temperature of the inlet manifold the temperature of the intake air charge is also reduced. The density of cooler air is greater than that of warm air. A denser intake air charge contains more oxygen which results in the potential for increased power and torque.

Each Cosworth Thermal Guard Composite Intake Gasket is precision manufactured from an engineering grade composite phenolic material that resists deformation common with plastic gaskets. As an added feature Cosworth Thermal Guard Composite Intake Gaskets are reusable and include a tube of "Hylomar Universal Blue Racing Formula" sealant. The use of OE inlet manifold gaskets is not required with the Cosworth Thermal Guard Composite Intake Gasket.
