Changing the spark plugs and sticking with the standard OEM ones. LMAR9E-j are the ones for my bike. Cost effective with Webike. Shipping is really good value if combined. Arrived in 100% condition and all plugs work great. Was a little worried there would be a duff but no, excellent. Fitting is hard as there is a lot to remove beforehand. Took a while but these new plugs have made the world of difference.

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. |
| 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. |

Best spark plug company ever!!
Purchased as replacements for my Yamaha MT10. These are the stock spark plugs but you simply cannot get any better than the NGK brand. Work every time, relatively easy to fit if you take a lot of parts off first lol.Yes, you can probably find fakes all over the internet but why risk paying around the same when you can buy the genuine ones from Webike and know you are getting exactly what you pay for.Easy to find on Webike's website. Shipping was average price, packaging, flawless as always. Arrived in one piece, no issues, bike runs brilliantly now.Thanks Webike

It seems to be a Plug for CROSSPlain.
It is the same as the one used by OEM and the quality is sure.
I just felt the price was too high.

I think you can't go wrong if you choose this one.
YZF-R1 (rn24j) It is used for
This is the first time I have ever replaced it.
I haven't had any problems with it so far.
I think I will use this product again next time as it is the only one that fits my R1.

Because it is a special product, there is only this choice of plug, and the price is 1600 yen, and the price is the same as Iridium plugs. Moreover, since it is about 1.4 times longer than ordinary plugs because of long reach, it has to be turned for a while.
As for the performance, because it is a special-purpose product, it is neither acceptable nor unacceptable. There was a thing with Gap of 0.7mmLimit and a thing that is over, though the corner of the electrode was standing when I looked at the Plug that ran for about 10000km.
Although the plug replacement standard of NGK is 3000-5000km and the owner's manual says it is every 13,000km or 12 months, I replaced it by the number of times when the plug ignited. The calculation formula is calculated with the replacement period (10,000km) = 5000 (10,000 for Iridium plugs) & divide; normal speed (rpm)
