Product Details
This is a Cometic Gasket Multi-Layer Steel (MLS) cylinder head gasket, specifically designed for BMW M54B25 and M54B30 engines. It features an 85mm bore and a compressed thickness of .066 inches, making it a solid option for rebuilding or repairing the top end of these popular BMW engines found in models like the 325i, 525i, and X5.
Cometic builds these head gaskets with multiple layers of stainless steel for increased strength and resistance to shearing forces, especially when mating aluminum heads to cast iron blocks. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing conditions and various surface finishes without needing additional sealants. The center layer is stainless steel and can be varied to achieve different thicknesses, like the .066 inches on this particular gasket, allowing for precise engine assembly.
