This is the NGK BR2LM spark plug, part number 5798. It has a solid copper core and a 99% pure alumina silicate insulator. A triple gasket sealing process stops gas leaking past the shell, corrugated ribs guard against flash over, and cold rolled threads protect the cylinder head. Silver chromate and zinc plating adds corrosion resistance.
Our take
Cold rolled threads are meant to protect the cylinder head, and corrugated ribs are there against flash over. Together with trivalent plating for corrosion resistance, they make this copper-core NGK a plug with protection built into its threads and body.
