Description
A ruthenium fine-wire center electrode and platinum ground electrode concentrate spark energy in this gasket-seat plug.
The center electrode uses 0.4 mm ruthenium-alloy fine wire, with a 0.8 mm platinum fine-wire ground electrode. Corrugated ribs resist flashover, an alumina-silicate ceramic insulator transfers heat, and the copper core aids heat removal. Trivalent metal plating provides corrosion and seizure resistance and eliminates the need for anti-seize.
