Cometic's MLS cylinder head gasket for BMW M54B25 and M54B30 engines (85mm bore) uses multiple embossed stainless-steel layers with Viton-coated outer faces and an uncoated stainless shim layer. At a compressed thickness of 0.045", it provides robust sealing for aluminum head-to-block or mixed-metal combinations, conforms to varied finishes, resists corrosion, and reduces required clamp load.
