NGK Spark Plug JR9C

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 standard plugs, including:

• Corrugated ribs to prevent flashover
• Superior strength and better heat transfer
• Copper core aids in heat removal
• Triple seals to prevent leakage
