The cross groove creates four small electrode which improves sparking performance and suppresses dispersion in voltage value, for an outstanding decrease in voltage required.
Iridium alloy – developed and patented by DENSO – offers a high melting point which dramatically improves wear resistance compared to other Iridium plugs.
360° laser welding is used to create a seal so reliable the electrode resists wear even under the most extreme engine conditions.
Using the same laser welding process as the Iridium Power spark plug, DENSO designed a long life spark plug for gas engines. With our patented Iridium alloy, DENSO was able to shrink the center electrode to 0.7mm, dramatically improving ignitability while maintaining longevity.
