Cometic BMW S54 3.2L 87.5mm 2000-UP .040 inch MLS Head Gasket M3/ Z3/ Z4 M

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 specifically designed to handle the demands of high-output engines like the BMW S54 3.2L, offering maximum sealing performance without the need for additional sealants. The stainless steel layers provide increased strength and resistance to corrosion, while the Viton coating can withstand temperatures up to 482 degrees Fahrenheit, making it suitable for various sealing environments and surface finishes.

The center layer of this gasket is uncoated stainless steel, allowing for precise thickness control. When compressed, this gasket measures 0.050 inches thick, with the bore size matching the 87.5mm specification for the S54 engine. This design is ideal for applications using aluminum heads with either aluminum or cast iron blocks, as it can effectively manage the shearing forces created between these dissimilar materials. It's a well-built component for rebuilding the top end of your M3, Z3, or Z4.
