Cometic BMW M50B25/M52B28 3.2L 85mm .066 inch MLS-5 325/525/328/528 M Head Gasket

When you're rebuilding the top end of your BMW M50 or M52 engine, getting the cylinder head sealed properly is crucial. This Multi-Layer Steel (MLS) head gasket from Cometic is built to handle the demands of these engines, whether you're dealing with aluminum heads on aluminum blocks or cast iron blocks. It's designed to provide a strong seal that can withstand the forces generated by different metal combinations.

This gasket is made 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). This coating ensures a reliable seal even under tough conditions and across various surface finishes. The center layer is uncoated stainless steel, and its thickness is what determines the overall compressed operating thickness of 0.066 inches, which is specified for your 85mm bore engine. Because it's an MLS gasket, it doesn't require any additional sealants, making installation more straightforward.

This Cometic gasket fits a range of BMW models including the 323i, 325i, 328i, 525i, 528i, and Z3 from the early 1990s through 2000. It's a well-built component designed for reliable performance in your engine rebuild.
