NGK Multi Ground Spark Plug

MAR10A-J

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.
