NGK BP6HS-10, stock number 6326, is a spark plug with a solid copper core and an insulator of 99% pure alumina silicate. A triple gasket sealing process is used to stop gas leaking past the shell. The plating is a trivalent finish of silver chromate and zinc, aimed at corrosion resistance. Each plug is supplied singly, so a multi-cylinder engine needs one for every cylinder.
Our take
The BP6HS-10 has a solid copper core and trivalent plating of silver chromate and zinc, which the maker credits for corrosion resistance. Corrosion resistance is the practical point of that plating on a boat engine, alongside the triple gasket seal at the shell.
