[Stock number] 95399 [Terminal shape] Screw type [NGK part number] SILMAR9B9 [Type] Iridium (Both precious metal type) [Heat Value] 9 .92070-0047 /
*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. *There may be changes in product specifications due to the manufacturer's reasons.
[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.
*Effectiveness may vary 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 plugs] - Super "wide-range" plugs The central electrode has a "copper-cored" structure with copper encapsulated close to 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 copper-cored and copper-coreless plugs, the copper-cored plug has superior thermal characteristics and stain resistance and a wider thermal range.
- High alumina porcelain of new ceramics is used for the insulator - ・Excellent insulation at high temperatures and reliable sparking. ・Excellent heat conductivity and prevents seizure. ・High thermal shock resistance (rapid heating and cooling) and excellent mechanical strength.
- The structure is strong and airtight The insulator and main metal fittings are joined by a special powder, making them airtight and structurally strong.
The electrodes are made of a special nickel alloy and are highly durable.
- Corrugations (folds) in the insulator ensure insulation and prevent flashover - During park, a high voltage is constantly applied between the terminal and the main fittings. 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 to spark between the terminal and the main fittings as shown in the image.

I was going to go for the standard OEM spark plugs for this service but when I saw the price of the iridium ones for the CBF1000, it was a no brainer to get these bad boys. These were easy to find using the tools provided by Webike and all the links to the manufactyrers websites.The cost was very good and purchased a set of 4.I have used iridium plugs before with great success as they seem to fire better than standard. I used EMS this time and everything arrived within a week. All packaged very well and no damage to anything in the order. Webike added additional bubble wrap for some of the parts to keep everything nice and snug. The plugs themselves are perfect. I have had some plugs befpre from overseas suppliers and generally, one of those had been a dud or just been broken during transit. Not this time. All 100% perfect and fired as they should. They do have a better performance than standard plugs but you would have to be a professional to actually notice the difference of the bat. Once fitted, the bike just feels smoother. Take your time and don't over tighten. One very happy customer. Thanks WebikeView Detail

i have always used NGK Iridium Plug CR9EHIX-9 4273 spark plugs they are the best for long run.i have used this spark plugs on my honda cbr xx superblack bird 1998 model they work very well no maintainance required.View Detail
I wanted to try out the iridium plugs on this old girl for my own peace of mind and to see if there is much difference between these and standard. These were easy to find using the tools provided by Webike and all the links to the manufactyrers websites.The cost was very good and purchased a set of 4. I have used iridium plugs before with great success as they seem to fire better than standard but never in this 2002 R1. I used EMS this time and everything arrived within a week. All packaged very well and no damage to anything in the order. Webike added additional bubble wrap for some of the parts to keep everything nice and snug. The plugs themselves are perfect.
