I wondered how much of a difference Iridium plugs would make, and replaced it, but there was no drastic change, and I felt good about the starting performance The vibration at the high RPM range is reduced and the impression is that it runs nicely at the high RPM range compared to the OEM Plug
Also, the XG250 TRICKER's downshift in the low rpm range is EngineStall has also been overshadowed by Iridium plugs compared to OEMs The lifespan is long, and I don't think this EngineStall has been around for a while
It is quite solidly made, and there is no Trouble of myself Plug cause, and use it safely Manufacturer who can
It is important to check the plugs periodically, because they have a long life span even though they are Iridium plugs It leads to Trouble

[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] |
| - 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. |
 |
| ■ Flashover |
| ■The advantages of the plug |

I am using it for FISEROW
I exchange it in one year, but the mileage is less than 5000? So I do not feel like getting better (Lol)
Even if it's hot or cold, it starts one shot! Both low and high revs turn smoothly
Since Windshield IRIDIUM is used only for the center electrode, durability is the same as that of Standard Plug BP 5 HA. I think
When exchanging the Plug I think that it will be better if the Air filter is exchanged together.

Since SEROW is easy to exchange, let's put it in immediately
Improve fuel economy of SEROW, launch Torque up. Although I do not know clearly yet, Plug basically exchanges with Windshield IRIDIUM. Considering the exchange Span and the price of the product, I think that it is the Custom that has the most effect than anything else.

It is attached to Yamaha's XG250 TRICKER, and it feels like Power is up.. I feel it in middle to high speed range. What is the durability after that?. I wish I could have three times.

I tried it by Plug exchange of the vehicle which traveled about 3500 km in mileage.
Work is very easy and soon it ended because it is SEROW.
Idling also did not feel much change when running normally, but I was surprised because it became easy to rise with the play of Front up which I do well.
I do not think that I got better, so I think that this plug.
Engine Power has gone up, it seems that the Engine has turned around well.
I was satisfied with quite a change, so I made a good evaluation this time.
