Ngk Spark Plug/solid

multi-ground electrodes improve ignition capabilities and are less sensitive to increased voltage requirements due to gap growth.

designed to specific manufacturer ignition requirements, ngks multi-ground plugs maintain all the features of their standard plugs, including:

corrugated ribs to prevent flashover

pure alumina silicate ceramic insulator, providing superior strength and better heat transfer

copper core to aid in heat removal

triple seals to prevent leakage
