The Cometic MLS head gasket for BMW M20B25/M20B27 is .095" thick with an 85mm bore and uses multiple embossed stainless steel layers. Outer layers are coated with Viton for heat-resistant sealing up to 250°C (482°F), while the center shim layer is uncoated stainless steel. MLS construction provides rebound and corrosion resistance, requires no sealants, and suits aluminum-to-aluminum or aluminum-to-iron applications.
