Cometic Gasket BMW S65B40 .036in MLS Cylinder Head Gasket - 93mm Bore

When you're rebuilding the top end of your 2008-2013 BMW M3, a reliable cylinder head gasket is crucial for sealing the combustion chamber. This Multi-Layer Steel (MLS) gasket from Cometic Gasket is built to handle the demands of high-output engines, ensuring a strong seal between your cylinder head and engine block.

This gasket is constructed from multiple layers of stainless steel, which gives it increased strength and the ability to rebound, helping it resist corrosion. The outer layers are embossed and coated on both sides with Viton, a heat-resistant rubber material designed for harsh sealing environments. The center layer is also stainless steel, allowing for precise thickness control. At a compressed operating thickness of 0.036 inches and a 93mm bore, it's designed to fit your M3's S65B40 engine perfectly. MLS gaskets are suitable for both aluminum-to-aluminum and aluminum-to-cast iron block configurations, and they don't require additional sealants.
