To increase ignitability, the important point is to let the flame kernel produced by the spark to grow unobstructed. Normally, this can be accomplished by widening the spark gap. However, this causes spark voltage to increase, which has the opposite effect. Iridium Power uses DENSO's patented U-Groove ground electrode to achieve maximum ignitability while minimizing required voltage.

プラグは大丈夫かと思いますが、箱がボロボロでした。片側は閉めても、勝手に空いてしまいます。これら運送時のダメージかもしれませんが、プラグという製品が押しつぶされてるのは少し気になります。まあ、安いのでよしとします。

取り付けて、少し走行しましたがキャブから燃料が漏れていました。早速ショップで見てもらったらこの商品は、旧車には向かないと言われました。旧車でなければ、すごくいい物らしいです。

ノーマルのプラグでは、信号待ちなどのアイドリング状態の時、たまにエンストする時が有りましたが、火花が強くなったためか、アイドリング回転が安定していて、今までより低い回転数にセットしてもエンストしなくなり、満足しています

いつもイリジウムを使っているため、違いがわかりません。何度リピートしているかわかりませんが、セルの音が変わったらいつも交換しています。だいたい5000kmです

These fit my 2007 BMW G650 motorcycle correctly and without issue. Order 2x plugs, due to the dual spark system.

This is a must have plug for the BMW F650 single spark with fuel injection. Makes it run like it should. I wouldn;t have believed it if I hadn't tried it myself!

I was using normal Harley Davidson plugs in my HD sportster 883R 2006 and ever since I have used these plugs there is a remarkable change in performance and fuel consumption. I definitely think these are worth using.

Following a fair amount of online research, I determined that Denso plugs were what I wanted. Having run Iridiums of another brand in my '89 Toyota pickup and '81 Goldwing for a number of years, I knew that they were all they claimed to be. Because Denso's have the u-groove in the ground electrode they produce a larger spark which translates into improved performance. While replacing the coils & wires on the bike with high performance parts, I wanted to go full bore and do the plugs as well.They're not cheap, but in my estimation it all comes back to you in the form of longevity and performance. The sum total of upgrades made a dramatic difference. While I can't give definitive numbers, I'm completely satisfied with the plugs and would happily recommend them to anyone.
