Cometic BMW M50B25/M52B28 85mm .060 inch MLS-5 325/525/328/528 Head Gasket

This is a Cometic Multi-Layer Steel (MLS) head gasket specifically made for BMW M50 and M52 engines. It features an 85mm bore and a compressed thickness of .060 inches, designed to provide a solid seal for high-output applications. Because it's a multi-layer steel design, it's built to handle the demands of both aluminum heads on aluminum blocks and aluminum heads on cast iron blocks without needing any additional sealants.

The gasket is constructed with multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are embossed and coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C) and works well with various surface finishes. The center layer is stainless steel, and its thickness can be varied to meet different requirements, which is how this gasket achieves its .060 inch compressed operating thickness.

This gasket is a well-built option for rebuilding or upgrading the top end of your BMW. It fits a variety of models including the 325i, 328is, 525i, and 528i from the early 90s through the late 90s and early 2000s.
