Product Details

The Cometic C4477-098 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for BMW M30B34 and M30B35 inline-six engines. This precision-manufactured gasket features a 93mm bore diameter and 0.098-inch compressed thickness, designed to provide superior sealing and durability in both stock and performance applications.

Key Features:

  • Multi-Layer Steel (MLS) construction for maximum strength and reliability
  • 93mm bore diameter designed for BMW M30B34 and M30B35 engines
  • 0.098-inch (2.49mm) compressed thickness for precise compression ratio control
  • Advanced embossment technology ensures optimal sealing around combustion chambers
  • Superior resistance to high temperatures and combustion pressures
  • Accommodates thermal expansion and cylinder head movement better than conventional gaskets
  • Reusable in many applications when properly installed and torqued

Cometic MLS head gaskets are the preferred choice for engine builders and performance enthusiasts working with BMW M30 engines. The multi-layer steel design provides excellent recovery characteristics and maintains clamping force under extreme conditions, making this gasket suitable for turbocharged, supercharged, and high-compression naturally aspirated builds.
