NGK 4548 CR9EK Multi-Ground Spark Plug

 OVERVIEW: 

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
