Cometic's MLS cylinder head gasket for BMW M42B18/M44B19 fits an 85mm bore with a 0.027 in gasket thickness to provide a reliable seal for rebuilt or high-output engines. Constructed from three to five stainless steel layers, the embossed outer faces are coated with Viton for heat resistance to 250°C (482°F). An uncoated stainless shim layer allows thickness variation while embossed layers improve load distribution and reduce clamp load to limit bore distortion.
