Product Details

The Cometic C4478-089 is a high-performance MLS (Multi-Layer Steel) cylinder head gasket engineered specifically for BMW S38B35 and S38B36 inline-6 engines. These engines were used in iconic BMW M models including the E34 M5 and E24 M6, making this gasket essential for rebuilds and performance applications.

Key Features:

  • Multi-Layer Steel construction provides superior sealing and durability under high compression and boost
  • Engineered bore size of 0.089" (2.26mm) thickness for precise compression ratio tuning
  • Coated with Cometic's proprietary surface treatment for enhanced sealing capability
  • Designed to withstand extreme cylinder pressures and temperatures
  • Direct replacement for BMW S38 engine family cylinder head gaskets
  • Ideal for performance rebuilds, forced induction applications, and high-RPM racing engines

Cometic gaskets are manufactured in the USA using advanced materials and processes, providing the reliability and performance demanded by professional engine builders and enthusiasts. This gasket eliminates the sealing issues commonly found with traditional composite gaskets when used in high-performance applications.
