The Cometic MLS head gasket for BMW M50B20 / M50B20TU (82mm bore, .080" thickness) is constructed from multiple embossed stainless steel layers with Viton-coated outer faces for heat-resistant sealing. The center shim layer is uncoated stainless steel to control thickness and clamp distribution. This MLS design reduces required clamp load and helps manage bore distortion while providing durable combustion sealing.
