The new DENSO® spark plug GE2-3 was developed specifically for use in high-end engine applications and is ideal for working with natural and specialty gases with its unique iridium alloy in the center and ground electrode. The newly designed copper-core protruding ground electrode provides improved heat dissipation and reduces wear on the electrode base material, resulting in increased electrical and mechanical durability and service life. The longer insulator design also offers the best protection against flashovers.

General Features

•      Longer insulator design offers the best flashover protection,
•      Suppression of electromagnetic interference (EMI),
•      Copper core ground electrode increases electrical and mechanical load capacity,
•      J type electrode design for improved combustion,
•      Improved spark erosion resistance.
