Product Details

The Cometic C4477-045 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 93mm bore diameter and .045" compressed thickness, providing exceptional sealing capability for both stock and modified applications.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • 93mm bore diameter engineered for BMW M30B34 and M30B35 engines
  • .045" (1.14mm) compressed gasket thickness
  • Stainless steel construction with advanced embossment technology
  • Accommodates thermal expansion and cylinder head movement
  • Ideal for high-performance, turbocharged, and supercharged applications
  • Reusable design when properly installed and removed

Cometic MLS gaskets utilize multiple layers of stainless steel with specialized coatings to create a superior seal that withstands extreme cylinder pressures and temperatures. The MLS design accommodates engine movement and thermal expansion better than traditional composite gaskets, making this gasket an excellent choice for BMW M30 engine rebuilds, performance upgrades, and racing applications.

Quick and easy

Ordered Epoxy 105 & hardener 205 for my composite slalom racing kayak repairs. I am from Europe and the product that I usually use is not available in US, so I used recommendation of the US dealer of the brand that makes my boats (Galasport) and ordered this. So I am sure it will work like a charm. And I find the pumping system quite sweet, looking forward to use it.. And I am impressed with the delivery speed, even during this corona outbreak, it was here deep in Montana countryside rightaway - ordered Thursday night, got it Monday afternoon. Thank you

I have no issues with Autoplicity, I ordered my item(s) hassle free, and it was delivered as expected. I will be shopping with them in the future for sure.
