The Cometic MLS cylinder head gasket for 2004–2006 Subaru EJ25 variants is a .060in multi-layer steel gasket with a 101mm bore. The MLS construction combines embossed AMP-coated outer layers with an uncoated stainless steel center/shim layer; the embossed outer layers accommodate harsh sealing environments and the shim center helps distribute clamp load while reducing bore distortion as noted in the specifications.
