Description

DENSO’s Iridium saver spark plugs are a range of high efficiency, long-life spark plugs for industrial gas engines that use iridium technology to increase plug life and performance; reducing maintenance costs achieved by the extended plug life in high pressure, lean-burn engines.

Using its patented Iridium alloy, DENSO was able to shrink the center electrode to 0.7mm, dramatically improving ignitability and longevity.

The DENSO difference:

  • High dielectric ceramics
  • Newly developed ceramics with finer grain, molded-in higher pressure and higher density prevents electrical breakdown of insulator.
  • Highly reliable monolithic resistor
  • Guaranteed high reliability for withstanding high combustion pressures by incorporating a stress resistant monolithic resistor that adheres to the resistor glass in the high temperature furnace.
  • In addition, this eliminates interference to electronic equipment from high energy coil noise.
  • Special Nickel plating with better corrosive resistance
  • Better corrosive resistance for condensed acid water.
  • Cross grove design (M18 mm Plug)
  • Four small electrodes create a cross groove which improves sparking performance and suppresses dispersion in voltage value, for an outstanding decrease in required voltage.
  • Unique Iridium Alloy
  • Iridium alloy – developed and patented by DENSO – offers a high welding point which dramatically improves wear resistance compared to other Iridium plugs.
  • 360 degree Laser welding
  • So reliable the electrode resists wear even under the most extreme engine conditions.
