Product Details

The Cometic C4394-056 is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket designed specifically for BMW M20B25 and M20B27 inline-6 engines. This gasket features an 85mm bore diameter and a compressed thickness of .056 inches, providing optimal sealing and reliability for both stock and performance applications.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • .056-inch compressed thickness for precise compression control
  • 85mm bore diameter engineered for M20B25 and M20B27 engines
  • Engineered to withstand extreme cylinder pressures and temperatures
  • Excellent for both OEM replacement and performance builds
  • Embossed stainless steel layers with elastomer coating for maximum conformability

Cometic MLS gaskets are the preferred choice for BMW enthusiasts and engine builders who demand reliability under demanding conditions. The multi-layer design allows the gasket to recover and maintain seal integrity through thermal cycling and engine movement, making it ideal for turbocharged, supercharged, or high-compression applications.
