The Skunk2 Thermal intake manifold gasket for B-Series Honda and Acura Ultra manifolds is a direct replacement gasket with a unique dual bolt pattern for Skunk2 Ultra manifolds only. Made from a high-temperature thermal polymer, it reduces heat transfer into the intake manifold to minimize incoming air temperature and heat soak. That reduced intake temperature can yield up to a claimed 5% power improvement in combination with cooler intake air, suitable for race, weekend or street use.
