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° Laser welding
- So reliable the electrode resists wear even under the most extreme engine conditions.
- Proving Longer Life
Using its patented Iridium alloy, DENSO was able to shrink the center electrode to 0.7mm, dramatically improving ignitability and longevity.
