**Even if you purchase in units of 10 pieces (1 box), it will not be delivered in 1 box.
*Terminals, tightening angle, etc. may differ depending on the model.Please refer to the link for the detailed fitting and installation instructions..
* The image is only for reference. The image shown may differ from the actual product.
| [Features of NGK plug] |
| - Super "wide range" plug - |
| The center electrode has a "copper cored" structure with copper sealed up to near the tip so that a large amount of heat can be released quickly. The result is an ultra "wide range" plug that is resistant to burning and smoldering. |
![]() |
| Comparing the thermal characteristics of plugs with a copper core and plugs without a copper core, plugs with a copper core excel in thermal characteristics and fouling resistance, and have a wider heat range. |
| ■ Heat value of the plug |
| - New ceramics high alumina porcelain 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 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. |
