Cometic BMW S50B30/S52B32 US ONLY 87mm .045 inch MLS Head Gasket M3/Z3 92-99

If you're working on the top end of your 1995-1999 BMW M3 or a 1998-2000 BMW Z3, this Multi-Layer Steel (MLS) head gasket from Cometic is built to handle the job. It's specifically designed for the US-spec S50B30US and S52B32 engines, featuring an 87mm bore and a compressed thickness of 0.045 inches. This gasket is engineered to provide a strong seal between your aluminum heads and either aluminum or cast iron blocks, resisting the shearing forces that can occur between different metals.

Cometic's MLS design uses multiple layers of stainless steel for increased strength and corrosion resistance. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C) and works well in various sealing conditions. This construction means the gasket doesn't require any additional sealants, making installation more straightforward. The center layer is also stainless steel, allowing for precise thickness control to meet specific engine requirements.
