The Cometic MLS head gasket for Mazda BP-4W/BP-ZE (84mm bore, .027in) uses three to five stainless steel layers with embossed outer faces coated in Viton for high-temperature sealing. Viton coating resists heat to 250°C (482°F). MLS construction provides strength, corrosion resistance, and rebound ability to meet demanding sealing environments for Mazda BP engines without sealants.
