Cometic MLS head gaskets for BMW M10B18/M10B20 engines are precision .027" multi-layer steel gaskets specified for 90mm bore applications and offered for 1972–1988 M10 engines. The MLS construction uses multiple embossed stainless steel layers with Viton-coated outer faces and an uncoated stainless center shim. These gaskets seal aluminum-to-aluminum and aluminum-to-iron joints, require no additional sealants, and are built to resist shear and corrosion while distributing clamp load evenly.
