Cometic MLS cylinder head gasket for BMW M10B18/M10B20 (.040-inch, 90mm bore) is built from layered embossed stainless steel with Viton coating on both outer faces for heat resistance to 250°C (482°F). The uncoated stainless shim layer allows thickness variation and the AMP outer treatment enhances sealing resilience. MLS construction improves load distribution, lowers clamp load requirements and helps prevent bore distortion in mixed-material assemblies.
