The Fel-Pro PermaTorque head gasket set for Mazda 6 (PT-7) is built to restore cylinder sealing in repair situations, using sealing technologies and proprietary coatings to handle imperfect mating surfaces. Its combination of durable facings, steel reinforcement and nonstick coating helps resist surface damage, while the steel-core design reduces the need for retorquing and offers validated fit for service replacements.
