Cometic BMW M20 2.5L/2.7L 85mm .140 inch MLS Head Gasket 325i/525i

This Cometic Multi-Layer Steel (MLS) head gasket is built with multiple embossed stainless steel layers, featuring an outer coating of Viton rubber. This construction is designed to handle the demands of high-output engines and is suitable for sealing aluminum heads to either aluminum or cast iron blocks, effectively managing the shearing forces that can occur between dissimilar metals. The compressed operating thickness of this gasket is .140 inches, with an 85mm bore, making it a precise fit for BMW M20 2.5L and 2.7L 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 material capable of withstanding temperatures up to 482°F (250°C), ensuring a reliable seal even in harsh operating conditions and across various surface finishes. The center layer is uncoated stainless steel and can be varied to achieve different thickness requirements. This gasket does not require additional sealants for installation.

This gasket fits a range of BMW models, including the 325e, 325i, 325iX, 325is, 525i, and 528e. It's a well-built component for rebuilding or replacing the head gasket on your M20 engine.
