Cometic Gasket BMW S65B40 .051in MLS Cylinder Head Gasket - 93mm Bore

When you're rebuilding the top end of your BMW M3, you need a head gasket that can handle the demands of that S65B40 engine. This Multi-Layer Steel (MLS) gasket from Cometic Gasket is built to provide a strong seal for high-output applications. It's designed to work with both aluminum and cast iron blocks, and its construction helps it resist the shearing forces that can occur between different block materials.

Cometic builds this gasket with multiple layers of stainless steel for increased strength and corrosion resistance. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit, ensuring a reliable seal even under tough conditions. The center layer is stainless steel and can be varied in thickness to meet different requirements; this particular gasket has a compressed thickness of 0.036 inches and a bore size of 93mm, designed for the specific needs of the S65B40 engine.

This gasket is intended for direct installation and does not require additional sealants, simplifying the assembly process. It's a well-built component designed to help you get your M3 back on the road with confidence.
