Cometic Gasket BMW M54B25/M54B30 .084in MLS Cylinder Head Gasket - 85mm Bore

If you're rebuilding the top end of your BMW M54B25 or M54B30 engine, a solid cylinder head gasket is crucial for a reliable seal. This Multi-Layer Steel (MLS) gasket from Cometic Gasket is built to handle the demands of higher output engines, ensuring a strong seal between your cylinder head and engine block without needing any additional sealants.

Cometic constructs this gasket using 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 different block and head materials, including aluminum and cast iron. The center layer is stainless steel and can be varied in thickness to achieve specific compression ratios; this particular gasket has a compressed thickness of .084 inches and an 85mm bore, designed to fit a range of BMW models like the 325i, 525i, and X5, as well as some Toyota Celica applications.
