Cometic's MLS cylinder head gasket for BMW M42B18/M44B19 is specified for an 85mm bore with 0.075 in thickness, engineered to maintain a reliable seal on rebuilt or upgraded engines. It combines three to five stainless steel layers with embossed outer faces coated in Viton for heat resistance to 250°C (482°F). The uncoated shim layer allows thickness variation while the embossed layers conform to surfaces, improve load distribution and reduce clamp load.
