Skunk2 thermal intake manifold gasket for D-series engines is a direct replacement that uses an advanced high-temperature thermal polymer to protect against heat soak and reduce heat transfer into the intake. By lowering intake air temperatures, this gasket helps provide cooler combustion air and can deliver up to about a 5% gain in power in some applications, while fitting Pro Series or OEM D-series manifolds.
