Description

• Description
  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, 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
