Cosworth Thermal Intake Manifold Gaskets (EJ25) Subaru WRX STI 04-12

Thermal Guard Composite Intake Gaskets are designed to aid in the reduction of inlet air temperatures by isolating the intake manifold from the heat generated by the engines cylinder head. By reducing the temperature of the inlet manifold, the temperature of the intake air charge is also reduced. A denser intake air charge contains more oxygen which results in the potential for increased power and torque.

Each gasket is precision manufactured from an engineering grade composite phenolic material that resists deformation common with plastic gaskets. As an added feature, the Cosworth Thermal Guard Composite Intake Gaskets are reusable and include a tube of "Hylomar Universal Blue Racing Formula" sealant.
