It was used with DJEBEL250 XC. I used LGType S before, and was satisfied with it, but I exchanged it for AR12ZS because the ignition system was NORMAL, and I thought that it would be more suitable.
The mileage is 12,000km. NGK or Denso Plug should be replaced earlier of course.
As for the FeeRing, it feels smoother than the Power feeling. The vibration is decreased. I felt that ZType S has less vibration than LGS which has good feeling at high rpm. But it's not better than OEM CR9E. It is only at the beginning that the FeeRing feels good.
I've been having some trouble around Idling lately, and when I disconnected the Plug, Big surprise!
The center electrode was worn about 2mm deeper than the insulator. The insulator itself is also crumbling.
I knew about this product from FACTORY Mameshiba's blog, and I thought this product would last 20,000km like LGType S. LGType S was used more than 10,000km, but the center electrode was not worn out. I was surprised that I could run in such condition.
Overall, the construction is rough, when I used LGType S, I broke Plug once, and there seems to be a thing which is not rigid enough. The surface treatment is also something cheap, or I cannot think very much to the Plug which costs 2,000 Yen per one.
If you use it, I think you should use it after inspecting at 1,000km to 3,000km span. In that case, please be careful enough about Overtorque. The fact that there are so many warnings in the product description column means that trouble is actually happening. If you use this product, please do so at your own risk.
I think I'll go with the RutheniumPlug next.
