The Cometic MLS cylinder head gasket for BMW M20B25 and M20B27 (85mm bore, 0.030in compressed thickness) uses multiple embossed stainless steel layers with Viton-coated outer faces to deliver robust sealing without sealants. MLS construction rebounds under load, resists corrosion, and accommodates aluminum-to-aluminum or aluminum-to-iron head/block combinations while the uncoated shim layer allows precise thickness control.
