This Cometic multi-layer steel (MLS) head gasket is made for BMW M42/M44 engines with an 86mm bore and .056 inch thickness. It uses multiple embossed stainless steel layers with outer layers coated in heat-resistant Viton rubber to handle harsh sealing environments and resist corrosion. The gasket is built to conform load distribution across the sealing area and to reduce clamp load and bore distortion in demanding engine applications.
