Multi-ground electrodes improve ignition capabilities and are less
sensitive to increased voltage requirements due to gap growth. Designed
to specific manufacturer ignition requirements in either supplementary
gap, intermittent discharge, or semi-surface discharge, all for various
firing tip self cleaning abilities. Multi-ground plugs maintain all
features of NGK's traditional plugs including corrugated ribs, pure
alumina silicate ceramic insulator for greater strength and better heat
transfer, copper core and triple interior seal.
2 different temperture ranges availabe
