Cometic Gasket BMW M54B25/M54B30 .089in MLS Cylinder Head Gasket - 85mm Bore

This Cometic Multi-Layer Steel (MLS) head gasket is built with multiple embossed layers of stainless steel, featuring an outer coating of Viton rubber. This construction is designed to handle the demands of high-output engines and is suitable for mating aluminum heads to either aluminum or cast iron blocks, resisting the shearing forces that can occur between dissimilar metals. The gasket has a compressed operating thickness of .036 inches and an 85mm bore, specifically suited for BMW M54B25 and M54B30 engines.

The strength of MLS gaskets comes from their layered stainless steel design, which allows them to rebound and resist corrosion. The Viton coating on the outer layers is a heat-resistant elastomer capable of withstanding temperatures up to 482°F (250°C), making it well-suited for harsh sealing environments and various surface finishes. The center layer is stainless steel and can be varied to achieve different gasket thicknesses, like the .089 inches of this particular gasket. These gaskets are designed to provide maximum sealing performance without the need for additional sealants.

This gasket fits a range of BMW models, including the 325Ci, 325i, 525i, and X5 from various years. It's a solid option for rebuilding the top end of your engine, ensuring a strong seal between the cylinder head and the engine block.
