Description
For maximum performance under the most extreme conditions, you can’t go past DENSO Iridium Power spark plugs. Through patented technology, including a 0.4mm diameter centre electrode - the Iridium Power plug produces the hottest, most concentrated spark with the lowest voltage and outperforms any plug today.
It is no secret that Iridium is 6 x harder, 8 x stronger and could take temperatures of 650 degrees C hotter than platinum (i.e. exceeding 2454 degrees C).
Through patented technology, including a 0.4mm diameter centre electrode - the Iridium Power plug produces the hottest, most concentrated spark with the lowest voltage and outperforms any plug today.
The DENSO difference:
- Iridium Power uses DENSO’s patented U-Groove ground electrode to achieve maximum ignitability while minimizing required voltage.
- At 0.4mm in diameter, the DENSO Iridium Power center electrode tip is the world’s smallest.
- Produces the hottest, most concentrated spark, while requiring the lowest voltage
- Produces maximum performance under the most extreme conditions
Laser Welding
There wasn’t a welding tool hot enough to melt an iridium electrode tip to a nickel base. That is until DENSO pioneered their patented Laser Welding Process that provides a 360° seal so reliable the electrode resists wear even in the worst conditions.
Improved Firing Performance
To improve firing performance, the contact area between the electrode and the flame nucleus needs to be reduced in size. This is why the electrode was made as fine as possible to a diameter of 0.4mm. Compared to normal Spark Plugs, with a spark gap of 0.8mm, the ignitability limits are better by 2.5.
Lower Required Voltage
The required voltage in the Iridium Power plugs is between 3 & 5 kv less than normal plugs. This is due to the ultra-fine 0.4mm diameter ground electrode and U-groove design. Because required voltage is kept low, Iridium Power can be used in high performance engines and for high response driving.
Smoother Idling
When an engine is idling, firing can become particularly bad. Because Iridium Power plugs have a low required voltage and high ignitability, sparking continues to work properly during idling. Whereas normal plugs have highly variable revolution counts, Iridium Power plugs maintain very smooth idling. Also, because combustion is good, the explosive energy raises the revolution count.
Improved Engine Performance
Iridium Power spark plugs enhance the performance of an engine. Acceleration is improved when compared against normal spark plugs.
Decreased Fuel Consumption
When Iridium Power spark plugs are used, accidental fire and misfiring rarely occurs under various driving conditions. Therefore, combustion is extremely good. In turn, a healthy engine can be maintained and fuel consumption improved.
