The Cometic MLS cylinder head gasket for BMW M42B18/M44B19 engines is a multi-layer stainless steel design sized for an 85mm bore and .089 inch thickness. Multiple embossed stainless layers are coated with Viton on both faces for heat resistance and sealing across varied surfaces; an uncoated stainless shim layer helps distribute load while reducing clamp requirements and bore distortion for improved sealing under demanding conditions.
