Product Details

The Cometic C4394-066 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for BMW M20B25 and M20B27 inline-six engines. This precision-manufactured gasket features an 85mm bore diameter and a compressed thickness of .066 inches (1.68mm), providing an excellent balance of sealing performance and compression ratio optimization.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • 85mm bore diameter designed for M20B25 (2.5L) and M20B27 (2.7L) engines
  • .066" compressed thickness for precise compression control
  • Embossed stainless steel outer layers with expanded graphite core
  • Resists blowout and provides exceptional combustion sealing
  • Accommodates thermal expansion and engine block movement
  • Ideal for both stock rebuilds and performance applications

Cometic MLS gaskets feature multiple layers of stainless steel with advanced coatings that adapt to surface imperfections while maintaining maximum clamp load. The MLS design allows the gasket to recover and seal more effectively than traditional composite gaskets, making it an excellent choice for BMW M20 engine rebuilds, performance upgrades, and forced induction applications.
