Product Details

The Cometic C4394-070 is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket designed specifically for BMW M20B25 and M20B27 inline-six engines. This high-performance gasket features an 85mm bore diameter and a compressed thickness of .070 inches, making it ideal for stock rebuilds or modified applications requiring reliable sealing under high cylinder pressures.

Key Features:

  • Multi-Layer Steel construction provides superior combustion sealing and durability
  • 85mm bore diameter designed for BMW M20 engine family specifications
  • .070" (1.78mm) compressed gasket thickness for precise compression ratio tuning
  • Embossed stainless steel layers with elastomeric coating ensure even clamping pressure
  • Excellent resistance to thermal expansion and combustion pressure cycling
  • Direct replacement for OEM gaskets with enhanced durability for performance applications

Cometic MLS gaskets are trusted by engine builders worldwide for their ability to maintain a reliable seal in demanding conditions. The multi-layer design allows the gasket to conform to minor surface imperfections while maintaining structural integrity under extreme temperatures and pressures. Compatible with BMW M20B25 (2.5L) and M20B27 (2.7L) engines found in various BMW E28, E30, and E34 models from the 1980s.

Great price and easy checkout.

Great customer service and support. a live person answered the phone and was able to reccomend the correct product for my vehicle. Best price online too........i woould most absolutely use them again! Great company!

I was very impressed by Autoplicity's customer service and excellent pricing on brand name products. Also, they provided lightning fast shipping even as the holiday weekend approached.<br>As much as I want to see everyone in this world to "live long and prosper," I was especially pleased to deal with a company that did not export their customer service to another country. <br>I look forward to doing business again with Autoplicity.

Just hope I get this shipped as fast as possible, we will see.

the Amazon payments feature was very slick.
