The Cometic MLS head gasket for BMW M20 2.5L/2.7L engines is a multi-layer steel design with embossed outer layers coated in Viton for heat-resistant sealing and corrosion resistance. Compressed operating thickness is 0.140" and the gasket uses a center uncoated stainless shim layer to accommodate thickness needs. MLS construction provides rebound and sealing across aluminum heads and cast iron or aluminum blocks without sealants, improving load distribution and reducing required clamp load.
