Product Details

The Cometic C4477-066 is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket designed specifically for BMW M30B34 and M30B35 inline-6 engines. This gasket features a 93mm bore diameter and a compressed thickness of 0.066 inches, providing exceptional sealing performance for both stock and performance applications.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior strength and durability
  • 93mm bore diameter optimized for M30B34 and M30B35 engines
  • 0.066-inch (1.68mm) compressed thickness for precise compression ratio tuning
  • Advanced coating technology ensures optimal sealing and gasket life
  • Accommodates thermal expansion and engine movement better than composite gaskets
  • Resists corrosion and provides excellent resistance to high combustion pressures

Cometic MLS head gaskets are the preferred choice for BMW enthusiasts and professional engine builders who demand reliability and performance. The multi-layer design allows the gasket to conform to imperfect sealing surfaces while maintaining consistent clamping pressure across the entire combustion chamber.

Search engine is messed up today. Overloaded maybe?

Was not thrilled about price, but, beggers can't be chosers.

Good so far!! Will make a complete review when I receive my item.

Initially your web site did not show option to PayPal upon checkout. I'm not sure how I finally got to the credit card option. This was mildly frustrating.

None

Thanks
