The Cometic C4348-027 is a precision-engineered multi-layer steel (MLS) cylinder head gasket designed specifically for BMW M42B18 and M44B19 engines. This high-performance gasket features an 85mm bore diameter and .027" compressed thickness, providing an excellent solution for both stock rebuilds and performance applications.

Key Features:

• Multi-Layer Steel (MLS) construction for superior sealing and durability
• .027" (0.69mm) compressed thickness for precise compression control
• 85mm bore diameter engineered for M42B18 and M44B19 engines
• Advanced embossment technology ensures even distribution of sealing pressure
• Enhanced resistance to combustion gases and coolant leaks
• Withstands extreme temperatures and cylinder pressures
• Allows for minor surface imperfections while maintaining excellent seal

Cometic MLS head gaskets feature multiple layers of stainless steel with advanced polymer coatings, providing maximum combustion sealing in demanding applications. The layered design allows the gasket to move with the engine's thermal expansion and contraction, preventing failure points common with traditional composite gaskets. Ideal for BMW E30 318i/318is, E36 318i/318is/318ti, and Z3 1.9 models equipped with these popular four-cylinder engines.
