The Cometic MLS head gasket for BMW M42/M44 engines fits 86mm bores with a compressed thickness of 0.066 inch. Comprised of multiple embossed stainless steel layers with Viton-coated outer faces, it resists corrosion and rebounds under load. The uncoated center shim allows controlled thickness, and the MLS design seals high-output engines without additional sealants for aluminum or mixed-head/block pairings.
