Using the high heat resistance of the iridium electrode, the spark position is protruded 0.4mm from the standard type.(1.6 to 2.0mm) For Honda vehicles only.
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.
Points of Attention
* If there may be an instruction manual included, it will be written in Japanese.
A friend of mine had a problem with his motorcycle not starting and not blowing well, so he consulted us and we looked at the plug and found that the electrodes were large and strange. He was happy to see that after the replacement, the blowing was much better. He was very happy to see that the car started and blew much better after replacing the electrodes.View Detail
may i 1st time using this denso iridium power plug for my motorcycle .it was power full and performance are best.i will recommend this quality and original product.,thanks webike...View Detail
Used in cb400sf nc39. Since the Normal plug completely failed, this time I got excited and I tried it as an Iridium plugs. Fuel economy, Power feels up. We plan to use this plug when we also exchange next!View Detail
We exchanged from Standard Plug BP 5 HA at about 11500?. I feel a sense of stability improved when Idling. I will do the same thing when I exchange next time as well.View Detail
Comprehensive comparison At Point, DENSO looks superior to Specifications from NGK, but DENSO seems to be more expensive than that. I tried picking DENSO after I got lost this time.
As impressions after installing the Plug, I was unfortunately insensitive to me, I did not feel the big difference with the Normal plug, but I am satisfied because the Plug became a new item and I could refresh moodily.View Detail
