Cometic MLS head gasket for BMW M50B20/M50B20TU engines is a .140 inch multilayer steel gasket with an 82mm bore. The MLS design uses embossed stainless steel layers coated with Viton on the outer faces to resist heat and corrosive conditions. Cometic notes the embossed outer layers and uncoated stainless shim layer provide improved sealing under varied loads while requiring less clamp load, helping control bore distortion across the sealing area.
