Cometic BMW M20 2.5L/2.7L 85mm .120 inch MLS Head Gasket 325i/525i

This Cometic Multi-Layer Steel (MLS) head gasket is built with multiple embossed stainless steel layers, featuring a Viton rubber coating on the outer layers. 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 is precisely 0.120 inches, with an 85mm bore, making it a solid option for BMW M20 2.5L and 2.7L engines.

The strength of MLS gaskets comes from their layered stainless steel construction, which allows them to rebound and resist corrosion. The Viton coating on the outer layers is a heat-resistant material capable of withstanding up to 482 degrees Fahrenheit (250 C), ensuring a reliable seal even in harsh operating conditions. The center layer is uncoated stainless steel, and its thickness can be varied to meet different sealing requirements. 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 325i, 325is, 525i, and 528e. It's a well-built component for rebuilding or repairing the top end of your M20 engine.
