bkr7eku multi-ground plug

multi-ground electrodes improve ignition capabilities and are less sensitive to increased voltage requirements due to gap growth. designed to specific manufacturer ignition requirements, ngk's multi-ground plugs maintain all the features of their standard plugs are 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 .
