The Cometic C4318-027 is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket specifically designed for Nissan RB25DE and RB25DET engines. This gasket features a compressed thickness of .027 inches and an 87mm bore diameter, making it ideal for stock and mildly modified applications.

Key Features:

• Multi-Layer Steel (MLS) construction provides superior sealing and durability
• .027 inch compressed thickness for precise engine specifications
• 87mm bore diameter engineered for RB25 series engines
• Advanced coating technology ensures optimal seal between head and block
• Designed to handle the thermal expansion and contraction of modern engines

Cometic's MLS gaskets utilize multiple layers of stainless steel with proprietary coatings to create a gasket that is both strong and flexible. This design allows the gasket to conform to imperfections in the sealing surfaces while maintaining excellent blowout resistance. The result is a reliable seal that can withstand the demanding conditions of high-performance and forced induction applications.
