This reusable thermal barrier intake gasket for the F20C/S2000 is made from a higher heat resistant polymer than other gaskets to reduce the chance of a melt down. Other brands are prone to "creep" which happens when the pressure of the manifold bolts causes the plastic to squish out when engine heat is applied. This 1/8"(3mm) thick gasket will help reduce thermal soak to the intake manifold that robs your engine of the cold air it needs to make power. Simple installation with average hand tools can produce results with no tuning required.
