【BRISK】Brisk ZC/ZS Plug [AR12ZS] Review

This Plug is not available

I installed them on my wr250x and felt no change from the NGK Iridium plugs. 7000km later the engine stopped at a stop light and would not start. I put the plug back in and the engine started fine. I will never use this plug again. View detail

The Ceramic part was shattered into pieces.

I've been using NGKIridium plugs until now, but since I don't run my engine much, I wanted to reduce the heat value, so I bought these. I was relieved to find that the plugs were compatible from 8 to 1.0, but after 10,000 km, I checked the Ceramic part and found that it was tattered. I'm sure it's a design that can't withstand the heat value of 8, so I think it's better to remove 9-10 CR10EK/CR9EIX compatible. I'm currently testing whether NGKWindshield IRIDIUM with a heat value of 8 can shatter ceramic. View detail

Trust and use BRISK!

Trust and use BRISK! I'm currently writing four dramas, I bought this out of curiosity, but there's a friend who's used this product. They say it's good! View detail

loss of central electrode

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. View detail

I enjoy the low to mid speed range.

It is necessary to pay close attention to the installation. This Plug does not have the feeling that Washer is crushed like a domestic new Plug.
There seems to be a feeling of tightening up as much as there are posts with screwy content.
Apply Thread compound on the screw part and use Torque wrench, 8.5 to 9.5Nm.
What do you think of it?
1 Engine application has been improved.
2 More Punch in the low to mid speed range and better Throttle response.
3 Increased fuel efficiency
I can't find any negatives so far.
Throttle is good and the Corner is very fun to start up.
The replacement from OEMPlug is It works. I feel that I have a lot to offer.
Because the high-performance Plug of Windshield IRIDIUMetc. has not been tried, the comparison of the feeling of use is not possible. View detail
