NGK 2305 Standard Series Multi-Ground Spark Plugs
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
