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 Cometic Multi-Layer Steel (MLS) head gasket is engineered to provide the ultimate seal for the legendary Mitsubishi 4G63 engine found in the Lancer EVO 4-9. With a compressed thickness of .051 inches and an 86mm bore, this gasket is designed to accommodate specific compression requirements while maintaining structural integrity under high-boost conditions. The MLS design is the preferred choice for professional engine builders due to its ability to handle extreme cylinder pressures.
Cometic's proprietary Viton coating on the outer layers ensures a perfect seal even on surfaces that are not perfectly smooth, making it ideal for aluminum heads mated to iron or aluminum blocks. This heat-resistant material can withstand temperatures up to 250°C (482°F), providing a robust barrier against combustion gases. The multi-layer construction allows the gasket to expand and contract with the engine's thermal cycles without losing its seal, effectively preventing leaks and blown gaskets in high-performance applications. If you are pushing your EVO to the limit, this gasket is an essential component for your engine build. Trust the reliability of Cometic Gasket for your next project, available at GGCRACING.
