The molded rubber material supports a stable seal at the fastener points, helping maintain proper compression between the valve cover and engine surface. If you are servicing a Nissan Frontier, Nissan Xterra, or Nissan Pathfinder, Mahle B31668 provides the correct sealing hardware for the application.
