[Features of NGK plug] |
- This is a super "wide range" plug - |
The center electrode , The center electrode is a "copper cored" construction with copper sealed to near the tip to allow a large amount of heat to escape quickly. The result is an ultra "wide range" plug that is resistant to burning and smoldering. |
Comparing the thermal characteristics of plugs with copper cores and plugs without copper cores, the plugs with copper cores have superior thermal characteristics and fouling resistance, and a wider thermal range. |
■ Heat value of the plug |
- High alumina porcelain from New Ceramics is used as the insulator - |
- Excellent insulation at high temperature and reliable sparking. ・Excellent heat conductivity and prevents seizure. ・High thermal shock resistance (rapid heating and cooling) and excellent mechanical strength. |
- Strong and airtight in construction - |
Because the insulator and the main metal fittings are joined by special powder, it is excellent in airtightness and strong in structure. |
Special Nickel alloy electrodes are used for superior durability. |
- Corrugations in the insulator ensure good insulation and prevent flashover - |
During sparking, a high voltage is constantly applied between the terminal and the main unit bracket. High voltages try to leak along the surface of the insulator and flashover is more likely to occur if the required voltage between the spark gaps is high. In order to prevent flashover, insulator corrugations (folds) are provided to increase the insulator surface distance between the terminal and the main fittings to ensure insulation and prevent flashover. |
What is a flashover... |
It is a spark between the terminal and the main unit fitting as shown in the image. |

It uses for 2021 YZ125X. The Plug which is originally encouraged by OEM is BR9EVX, but the price is a little high in Windshield IRIDIUM, and there is also the fact that it is exchanged immediately when it is covered, so I am using Normal plug. I tried Standard Type No.9, but it was No.8 that I felt stable in any situation. I also tried Standard Type No.9, but I feel No.8 is more stable in any situation. However, I feel No.9 is more stretchable in Motocross course with high rpm. Because there is a lot of all-round use recently, I thought that it was here.View Detail
2-StokeEngine and BR8ESPlug are strong for CUB re.
This is Data after a long time of use.View Detail
I used it in the 2nd HusabergTE125 Plug.
I think the 2ndRacer with mixed oil is fine with this regular Plug, I feel like I'd be better off replacing the regular Plug with a new state of blistering than the Racing plug or Windshield IRIDIUM.

I used it to replace the Plug periodically on my CRM250RR. 2ST has a lot of ignition times, so I also used a spare I bought it including There is no problem at all NGKView Detail
