The Cometic MLS‑5 head gasket for Nissan SR20DE/DET (S13) is a multi‑layer steel gasket with an 87mm bore and a .056in thickness, featuring an extra oil passage at the rear. Composed of multiple embossed AMP‑coated and uncoated stainless steel layers, the gasket is designed to conform to varied sealing environments and surface finishes. The uncoated stainless shim layer allows thickness variation while reducing required clamp load and helping distribute sealing loads across the joint.
