Product Details

The Cometic C4394-045 is a premium Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for BMW M20B25 and M20B27 engines. This high-performance gasket features an 85mm bore diameter and .045" (1.14mm) compressed thickness, delivering exceptional sealing capability for both stock and modified applications.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior strength and durability
  • 85mm bore diameter precisely sized for M20B25 and M20B27 engines
  • .045" compressed thickness provides optimal sealing compression
  • Accommodates thermal expansion and minor surface imperfections
  • Suitable for both stock and performance applications
  • Compatible with turbocharged and high-compression builds

Cometic's MLS gaskets utilize multiple layers of stainless steel with advanced coating technology to create a gasket that can withstand extreme cylinder pressures and temperatures. The embossed layers allow the gasket to respond to the unique sealing requirements of both the combustion chamber and coolant passages, making it an ideal choice for BMW M20 engine rebuilds and performance upgrades.

Applications: BMW M20B25 (2.5L) and M20B27 (2.7L) inline-6 engines found in E28, E30, and E34 chassis vehicles from the 1980s and early 1990s.
