MLS Head Gasket 0.036" x 84mm Bore

The Cometic C4278-089 is a Multi-Layer Steel (MLS) head gasket engineered to provide maximum sealing performance for high-output engines. This gasket is constructed from multiple embossed layers of stainless steel, with the outer layers coated in Viton rubber, a heat-resistant elastomer capable of withstanding temperatures up to 250°C (482°F). The center layer is uncoated stainless steel, allowing for varied thickness requirements. Designed with an 84mm bore and a compressed operating thickness of 0.036 inches, this MLS gasket offers increased strength and resistance to corrosion due to its multi-layer stainless steel construction, which also provides rebound capabilities. Cometic MLS gaskets are ideal for both aluminum-to-aluminum and aluminum-to-cast iron block configurations, effectively withstanding shearing forces. This head gasket is specifically designed to fit a range of vehicles, including the 1987-1992 Toyota Supra (Base and Turbo models) and the 1989-1992 Toyota Cressida (Luxury submodel). It also fits various Jaguar XK models from 1949 to 1961. Please verify fitment for your specific vehicle.
