Looking to provide the best performing thermal insulation gasket, SiriMoto started development of their Thermal Intake Manifold Gaskets. A simple part that will pay huge dividends whether you race your vehicle regularly, or are simply looking to have an edge on the competition. The state-of-the art gasket material that SiriMoto chose works by diminishing the conveyance of heat from the cylinder head to the intake manifold. This attenuation of heat helps to provide a cooler air charge that will better mix with fuel and provide a stronger/more powerful combustion event.

Key Features:

• Increases horsepower by greatly reducing heat transfer from the cylinder head to the intake manifold.
• Designed as a direct replacement to the factory gasket.
• Made from the best heat dissipating material known for automotive use. It basically creates a "thermal barrier" that hardly any heat can pass through.
• Rated up to 500 deg. F.
• Thoroughly track tested in very hot weather.
• Covered by SiriMoto's 1 Year Limited Warranty.
