Product Details

The Cometic C4477-120 is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket designed specifically for BMW M30B34 and M30B35 inline-six engines. This gasket features a 93mm bore diameter and .120" (3.05mm) compressed thickness, making it ideal for stock rebuilds or mild performance applications.

Key Features:

  • Multi-Layer Steel construction provides superior sealing and durability
  • 93mm bore diameter designed for M30B34 and M30B35 engines
  • .120" compressed thickness for proper compression ratio
  • Embossed stainless steel layers with elastomer coating
  • Accommodates thermal expansion and engine movement
  • Reusable design allows for multiple installations
  • Exceeds OEM specifications for reliability

Cometic's MLS gaskets utilize multiple layers of stainless steel with advanced coating technology to create a superior seal between the cylinder head and engine block. The design allows the gasket to recover and maintain optimal sealing pressure even under extreme temperature cycling and combustion pressures. This gasket is compatible with BMW M30 engines found in various 5-series, 6-series, and 7-series models from the 1970s through early 1990s.

Love the Amazon pay option. Best price I could find on the net was through autoplicity. Great service thus far.

This is the first time I've ordered from Autoplicity. I found they had the best price on the item I was looking for and decided to try them. I ordered this item yesterday(Sunday) and was just informed that it shipped. That is quick. I am pleased with their customer service and will use them as my first source.

Best price I can find on my item and fast shipping. Thinking about becoming a member to order all my parts for my racing team.

Had by far the cheapest place on the internet for the part I was looking for! Shipping was extremely fast as well! A++

All pieces ordered were shipped promptly and arrived in very great shape. I will be ordering from this site again.

Good prices. Good communication.
