The DDI spark plug is particularly effective when used in biogas engines. Try DENSO DDI spark plugs today.

The SAVERʼs Key to Long Plug Life

DENSOʼs OEM expertise and commitment to innovation enables them to remain at the forefront of cutting-edge gas engine spark plug development. The unique and specialist technology used in the Iridium Saver and Iridium Saver Performer spark plugs range extends their lifespan, making them ideal for high-compression lean-burn engines. Iridium Saver and Iridium Performer spark plugs also help to maximise engine performance and deliver extra durability. Because they require minimal maintenance compared to standard plugs, Iridium Saver and Iridium Saver Performer spark plugs increase service interval times.

The new DENSO® spark plug GE2-3 was specially developed for use in state-of-the-art engine applications and, with its unique iridium alloy on the center and ground electrode, is ideally suited for operation with natural and special gases. The new designed, protruding ground electrode with copper core provides improved heat dissipation and reduces wear on the electrode base material, resulting in increased electrical and mechanical strength and service life. The longer insulator design also offers the best protection against flashovers.

General Features

  • Longer insulator design offers best flashover protection
  • Suppression of electromagnetic interference (EMI)
  • The ground electrode with copper core increases the electrical and mechanical load capacity
  • J-type electrode design for enhanced combustion
  • Advanced spark erosion resistance
