This 12VDC relay keeps the auxiliary cooling fan running for a set period after engine shutdown, allowing residual heat to dissipate from critical components. It manages fan operation independently of ignition status, preventing heat soak that can affect electrical and engine system reliability. By extending cooling time after operation, the NGK Spark Plugs S81NL relay supports more stable temperatures in tightly packaged engine bays.
