Cometic Gasket BMW M20B25/M20B27 .068in MLS Cylinder Head Gasket - 85mm Bore

Cometic Gasket is known for making well-built sealing components for performance applications. This Multi-Layer Steel (MLS) head gasket is built to handle the demands of high-output engines, making it a solid option for your BMW M20B25 or M20B27 engine. It's designed to provide maximum sealing performance without needing any additional sealants, which simplifies installation.

This gasket is constructed from 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 harsh sealing environments and varying surface finishes. This construction is suitable for mating aluminum heads to either aluminum or cast iron blocks, as it can withstand the shearing forces that can occur between different metals. The center shim layer is stainless steel, allowing for precise thickness control, and this particular gasket has a compressed operating thickness of 0.068 inches with an 85mm bore diameter.

This gasket fits a range of BMW models including the 325 series (like the 325i and 325is) and the 525i. It's a well-made component designed for reliable sealing in performance applications.
