Cometic C5111-036 BMW MLS Cylinder Head Gasket Bore - S65B40 93mm 036

The Cometic C5111-036 is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket designed specifically for the BMW S65B40 high-performance V8 engine. This gasket features a 93mm bore diameter and .036" (0.91mm) compressed thickness, making it ideal for stock replacement or performance engine builds.

Key Features:

• Multi-Layer Steel construction provides superior sealing and durability under extreme temperatures and pressures
• 93mm bore diameter precisely matches S65B40 engine specifications
• .036" compressed thickness allows for proper compression ratio management
• Stopper layer embossment around combustion chamber and fluid passages prevents leakage
• Coated with a proprietary gas-tight sealing compound for enhanced sealing performance
• Designed to accommodate thermal expansion and engine movement without failure
• Direct fit for BMW M3 E90/E92/E93 (2008-2013) equipped with S65B40 engine

Cometic's MLS technology uses multiple layers of stainless steel with embossed sealing beads that maintain constant sealing pressure across the entire gasket surface. This design is particularly beneficial in high-output applications where conventional composite gaskets may fail.
