SpeedFactory is proud to announce that we have redesigned the popular thermal intake manifold gasket. SF gaskets are designed to be used as a direct replacement for the OEM intake manifold gasket. The purpose of the gasket is to significantly reduce the transfer of heat from the head to the intake manifold. By doing so you are dropping the temperatures inside the intake manifold and also producing more power because of the drop in temps.

SF has seen up to 40% increase in intake manifold temperatures without the use of a thermal gasket.

Here is a useful fact: For every 3.3°C (5° F) rise in intake temperature, air density drops 1%. The hotter the air, the less fuel the computer injects to compensate for reduced oxygen.
