The Cometic MLS head gasket for Nissan RB25DE/RB25DET (86.5mm, .060) uses multiple embossed layers combining AMP coating and uncoated stainless steel for robust sealing. The embossed outer layers meet harsh sealing demands while the uncoated stainless shim layer allows varied thicknesses, requiring less clamp load and improving load distribution across the sealing area for reliable head sealing under varied conditions.
