The spark gap is wider than the standard type (from 0.8 to 0.9 mm), taking advantage of the low spark voltage of the 0.4 mm diameter iridium center electrode.Further improved ignition performance. For Yamaha, Kawasaki and other motorcycles, FERARRI, MASERATI, ALFA ROMEO.
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

This is the second time I've used this product. At 19,000 km, the NGK Standard Plug BP5HA, which was installed from the time of delivery, was replaced with NGK's Iridium plugs at 19,000 km It's a different kind of power. I chose Denso because of its reputation as a It's true that compared to NGK, each explosion seems to be more powerful and has more power. I noticed that after about a year and a half of driving about 1,000 miles, the Idling was starting to have some Rose on it. (Only to the extent that one segment of Tachometer, which divides the 1000 rpm into four segments, blinks. The Manufacturer's website recommends that motorcycles should be replaced at 5,000 km. I bought the same Denso because I thought it would be time to replace it if it was 10,000 kilos, even if I was exaggerating Large. It's more expensive than the NGK at 2,200 yen per bottle, but it's a single cylinder so I don't mind. The replacement takes 5 minutes with the Plug socket & ratchet wrench if you remove the Radiator shroud on the Left Side. When I used to drive a BMW, I got fed up with the quality of the OEM specified Champion and Bosch plugs and measured the reach and protrusion and used the same thermal value NGK to solve the problem. "Plug is ngk. But I feel that Denso is also something to be reckoned with.View Detail
I used NGK's Iridium plugs which have different heat values ??so far. Because it was a single cylinder using about 10,000 kilometers, I was thinking about replacing it soon. Why you made it to DENSO is the price. It was simply easier than NGK, but the performance is outstanding. Engine rotation becomes smooth. Obviously you can realize the effect of the exchange. It's the best of Cospa and I definitely want to recommend it.View Detail
Used for 99 year model KLX 250. Until now I have been using NGK's OEM count, I was plagued by the poor startability peculiar to this car model But when I replace Windshield IRIDIUM I feel a clear improvement in startability. Almost no stalls occurred frequently in the vicinity of Idling. I do not know if the setting changed because the season changed, but at least I do not give any negative influence. View Detail
I switched from OEM to Iridium plugs by MAJESTYS Plug exchange. It is a change in the sense of insurance because it will not drop to less than 5000 revolutions without opening Axel in the NORMAL state. Startability is originally good so I do not know the change. If it does not change durability, it may be returned to OEMPlug next time. View Detail
