Fel-Pro Mitsubishi Diamante HS 26193 PT-1 PermaTorque Engine Cylinder Head Gasket Set

The steel core in this Fel-Pro PermaTorque head gasket set is a key feature, helping to eliminate the need for retorquing head bolts after installation. This is important because a proper seal between your engine block and cylinder head is critical for keeping combustion gases contained and coolant and oil separate. When you're working on your 1997-2004 Mitsubishi Diamante, using a gasket designed for the realities of the repair environment can make a big difference.

Fel-Pro builds these gaskets with proprietary materials and unique design features specifically for imperfect sealing surfaces. They often include a graphite or reinforced fiber facing, along with steel armor for added strength and durability. Plus, a nonstick anti-friction coating is applied to help seal small scratches or imperfections on the mating surfaces, ensuring a more reliable seal right from the start. This approach means you can count on a solid seal without needing to worry about the extra step of retorquing.
