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:
- Sold separately
- 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
