Cometic Gasket is the world leader in custom multi-layer steel head gaskets for performance and motorsport engines. From off-the-shelf MLS for popular platforms to bespoke gaskets for race-only builds, Cometic seals everything from Honda B-series to LSX.
The 7MGTE engine is a legend, but it is notorious for head gasket failures. Solve this issue once and for all with the Cometic Multi-Layer Steel (MLS) head gasket. Specifically designed for the 84mm bore 7M engine, this .051-inch thick gasket provides the robust sealing surface required to handle increased boost and high-performance driving conditions.
Cometic MLS gaskets utilize multiple layers of stainless steel to create a gasket that can withstand the shearing forces created by the engine block and head. The outer layers are embossed and coated with Viton, a high-performance fluoroelastomer that conforms to surface imperfections, ensuring a perfect seal without the need for additional sealants. This gasket is the definitive upgrade for any 7M engine build, whether you are restoring a classic Supra or building a high-horsepower turbo setup. Don't let a blown gasket ruin your engine—trust the proven performance of Cometic gaskets. Enhance your vehicle's reliability and power with premium parts from GGCRACING.
