This precision-manufactured gasket features a .140-inch (3.55mm) compressed thickness and an 85mm bore diameter, making it ideal for both stock rebuilds and performance applications.

Key Features:

• Multi-Layer Steel (MLS) construction for superior sealing and durability
• .140-inch compressed thickness provides optimal compression ratio control
• 85mm bore diameter designed for CA18DE and CA18DET engine blocks
• Embossed stainless steel layers with advanced coating technology

Cometic MLS gaskets utilize multiple layers of stainless steel with proprietary coatings to create a gasket that conforms to imperfections in the sealing surface while maintaining extreme durability. The .140-inch thickness makes this gasket suitable for mildly modified engines or as a quality replacement for stock applications. Proper surface preparation with an RA finish of 50-60 is recommended for optimal sealing performance.
