P2R Power Rev Racing throttle body gaskets will help reduce intake air temps by removing the direct connection of the throttle body to the intake manifold. By placing this thermal gasket between the throttle body and the intake manifold, you will help reduce the amount of heat soak the intake manifold normally absorbs.
