The Z125PRO seems to have some individual differences and some guys seem to have a bad Engine start, but mine is one of them!
I added iridium to try to improve it a little, but it only made it start a little better.
I'm going to skip this because it's only a plug level …, but it seems to have some effect.
If it's a solid vehicle, the effect could be felt.

[Features]
1. Improved acceleration
You can feel the difference between this plug and the standard plug by its quick response to the accelerator pedal opening.Changing to Iridium plugs will improve acceleration.
2. Engine power pup
Iridium plugs increase engine performance.You can enjoy a comfortable ride with a strong power on the uphill.
3. Improved ignitability and startability
Iridium plugs have ultra-fine electrodes that ignite quickly and improve the starting performance of the engine.The idling is stable because of less spark variation.
4. Increased fuel efficiency
Iridium plugs have excellent ignitability, so they burn gasoline efficiently.This plug is both economical and environmentally friendly.
As a premium plug for stock engines, an ultra-fine iridium alloy has been adopted for the central electrode to achieve superior ignitability and greatly improved response.The electrode is thin and sparks fly easily, so the energy is large and the ignitability is improved.It maximizes the performance of the engine.In addition, the thermo edge at the tip of the insulator burns off the attached carbon (burnt debris), prevents the ignition performance of the plug from deteriorating, and maintains high performance.
[Features of Iridium IX plug]
Iridium IX plugs are high performance plugs with a faster combustion spread than general plugs and with a thermo edge at the tip of the insulator to improve plug fouling.
Iridium alloy is used for the center electrode.
The electrodes are finer than those of platinum to improve the ignition performance.In addition, this plug is resistant to carbon contamination by the thermo edge effect.
・The center electrode is very thin and the tip of the outer electrode is tapered.
・Easy to spark and excellent in ignition performance.
・The engine has improved starting performance, acceleration, idling stability, and fuel consumption.
・Since the flame damping effect of the plug electrode is reduced, the ignition performance is improved.
*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. |
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. |
