Stable ignition performance and combustion efficiency at a reasonable price.It brings out the true performance of the engine.
[Features of Register plug]
A ceramic resistor is built in to suppress the ignition noise generated at the time of spark.
・The built-in ceramic resistor suppresses the ignition noise generated by the spark.
・Prevents radio noise in car radios, mobile hams, and car telephones.It also prevents the engine control computer from malfunctioning due to noise.
*The effect varies depending on the vehicle.
[About the shape of the plug terminal]
●Select a terminal shape that matches the engine and plug cord installation side.
There are three types of plug terminals: integrated type, separate type, screw type, and punch-and-caulk type.
Mainly, "integral type" and "punch caulking type" are used for four-wheeled vehicles and "screw type" for two-wheeled vehicles, and "separate type" is available for plugs used for both four-wheeled and two-wheeled vehicles.
In addition, the terminal part of the "separate type" can be removed, but the terminal part of the "integrated type" and "punch-and-caulk type" cannot be removed.If you try to remove it forcibly, the terminal part may be broken.
In case of using the "separate type" as the "screw type", remove the terminal nut.
When using the product with the terminal nut attached, make sure that it is not loose, and if it is loose, tighten it lightly with pliers or the like.
| [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. |
| - Excellent durability - |
| 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. |

| ■ Flashover |

install on honda dio 70cc tuned
Works fine , nothing to adjust. It looks like an original NGK spark plug. On my honda dio af27 70cc at first ride a feel my litle pussycat transform in to a lion (probably the old ngk sparkplug was a chinese fake)

Features a different base style compared to the original plug
Quality and Texture:The NGK CR8E is a standard resistor-type spark plug with a heat rating of 8. As expected from NGK, the plug is manufactured with high-quality materials and precise engineering, ensuring reliable performance and durability.Feeling of Use:This spark plug features a different base style compared to the original plug in my engine. I was looking for slightly more clearance and a cooler rated plug and the CR8E has achieved both these goals.Recommended Accessories:Since spark plugs are regular maintenance items, I suggest purchasing related consumables like crush washers, gaskets, and other small engine service parts. These items are inexpensive, readily available, and useful to have on hand during routine maintenance.Installation Difficulty:Installation was straightforward and took approximately 0.2 hours. With some basic mechanical knowledge and standard hand tools, it’s easy to check the electrode gap and install the plug correctly. A feeler gauge is recommended to ensure the gap is within spec.Cost Performance vs. Competitors:NGK offers excellent value across their product line, and the CR8E is no exception. Compared to offerings from other manufacturers, this plug delivers solid performance at a competitive price.Shipping and Packaging:I opted for EMS shipping, as there was no price difference between sea freight and EMS, and I wanted quicker delivery. The spark plug was very well packaged, protected with bubble wrap and air pillows inside a sturdy cardboard box.Concerns or Advice:When shopping for motorcycle parts, Webike Japan is my go-to source. Their wide selection, competitive prices, and reliable shipping make them a solid choice for both routine service items and performance upgrades. Always ensure compatibility with your specific engine model before ordering.
