Product Details

The Cometic C4477-075 is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket designed specifically for BMW M30B34 and M30B35 inline-six engines. This high-performance gasket features a compressed thickness of .075 inches (0.075") and is manufactured with a 93mm bore diameter to provide optimal sealing for both stock and performance applications.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • 0.075-inch compressed gasket thickness for precise compression ratio tuning
  • 93mm bore diameter engineered for M30B34 and M30B35 engines
  • Advanced embossment technology ensures even torque loading and combustion sealing
  • Exceeds OEM specifications for high-performance and forced induction applications
  • Compatible with turbocharged, supercharged, and naturally aspirated builds

Cometic MLS gaskets utilize multiple layers of stainless steel with specialized coatings to accommodate thermal expansion and engine movement while maintaining optimal cylinder sealing. The embossed layers provide micro-sealing around combustion chambers, coolant passages, and oil galleries. This gasket is ideal for engine builders seeking reliable performance in street, track, or boosted BMW M30 applications.
