The Cometic C4278-040 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Toyota 7M-GE and 7M-GTE engines. This gasket features a compressed thickness of .040 inches and an 84mm bore diameter, making it ideal for both stock rebuilds and performance applications.

Key Features:

• Multi-Layer Steel (MLS) construction for superior sealing and durability
• .040 inch compressed thickness provides reliable sealing with slightly increased compression
• 84mm bore diameter designed to match 7M-GE and 7M-GTE cylinder specifications
• Embossed stainless steel layers with Viton rubber coating for exceptional heat and chemical resistance
• Engineered to withstand extreme cylinder pressures in turbocharged 7M-GTE applications
• Reusable design allows for multiple engine assembly cycles

Cometic MLS gaskets are a trusted choice for Toyota Supra enthusiasts and engine builders working with 7M series engines. The multi-layer construction allows the gasket to recover and maintain torque loading better than traditional composite gaskets, making it especially suitable for high-boost turbocharged builds where cylinder pressure and thermal cycling are concerns.
