Cometic MLS head gasket for Porsche 997 3.6L twin-turbo engines is specified for a 102mm bore at .040" thickness. The gasket uses multiple embossed stainless steel layers with Viton-coated outer faces to resist heat and corrosion; a central uncoated shim layer accommodates thickness requirements. MLS construction allows reduced clamp load and improved sealing between dissimilar metals without sealants, meeting harsh sealing demands.
