Product Details

The Cometic C4394-140 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for BMW M20B25 and M20B27 engines. This precision-manufactured gasket features an 85mm bore diameter and .140" (3.6mm) compressed thickness, providing superior sealing and durability for both stock and performance applications.

Key Features:

  • Multi-Layer Steel (MLS) construction for maximum strength and reliability
  • 85mm bore diameter designed for M20B25 and M20B27 engine blocks
  • .140" compressed thickness for proper compression ratio
  • Superior heat dissipation and resistance to extreme temperatures
  • Excellent resistance to blow-out and gasket failure
  • Reusable design allows for multiple installations when properly maintained
  • Precision-engineered to meet or exceed OEM specifications

Cometic MLS gaskets utilize multiple layers of stainless steel with advanced coating technology to create a gasket that conforms to imperfections in the head and block surfaces. This design accommodates thermal expansion and contraction while maintaining consistent sealing pressure across the entire combustion chamber. Ideal for BMW E30, E28, and E34 models equipped with M20 inline-six engines.

I ordered a set of inner tie rods for my car from Autoplicity and found their prices to be the lowest online for the brand I was looking for. Items were ship out in 2 business days from the original manufacturer. Shipping prices were kind of on the expensive end considering the package size and weight so if Autoplicity adjust their shipping prices to be more competitive, I think their service and pricing would be hard to beat!

Wow talk about FAST shipping...I placed the order...and the door bell rang for delivery!!! The electronic points and coil when in the FJ 4o in just a few minutes and work perfectly...THANKS so much! Larry in Montana

Great pricing and quick shipping. I'll be using them again for sure.

Hard to find part in stock I hope
