Overview
Suitable for use on all Hemi 6 engines running factory exhaust manifold or Pacemaker extractors.
HP Premium Graphite Manifold Gaskets
These gaskets offer a superior seal when compared to traditional composite type. They have an optimum 'crush' value ensuring a tight seal; this is especially good for extractors, but still able to be used on standard factory manifolds with great results!
Made from a perforated stainless steel insert sandwiched between two layers of flexible graphite to ensure that they have a super high heat tolerance like no other aftermarket gasket.
These gaskets can be opened up with a die grinder for ported heads and still maintain enough material to seal properly. This makes them ideal for turbo & supercharged applications.
