Iridium power to further increase your vehicle's acceleration and fuel efficiency with stable ignition power.It is recommended for those who want to have a higher grade of sharpness and power in their vehicle, and for those who want to drive economically with good fuel economy.

[In addition to the high response, the acceleration performance is improved.]
Iridium power ensures stable ignition even when the engine is running unevenly.This improves the performance during acceleration.

[More reliable ignition at idle]Fuel efficiency and quietness are also improved.]
Iridium Power reduces missparks and stabilizes idling speed at idle, where ignition is often poor.This increases the quietness of the engine noise and fuel efficiency.

[0.4mm diameter iridium alloy center electrode]
The thicker the center electrode of the plug is, the larger the cooling effect becomes and the worse the ignitability becomes.In comparison, the 0.4 mm diameter iridium alloy center electrode has an extremely small cooling effect and heat is not easily lost, so that ignition loss is reduced and more reliable ignitability, which can be called the basic performance of the plug, is realized.

[uneven ignition power]
For the improvement of ignitability, it is important to grow the flame nucleus formed by the flying flame.Normally, this is done by increasing the spark gap, but this increases the sparking voltage and has the opposite effect.Therefore, DENSO's original U-groove grounding electrode was adopted for Iridium Power, and excellent ignition performance was realized while keeping the spark voltage low.
