[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. |

Standard spark plugs that can be installed on the KTM 1290 Super Adventure. The engine will use 4 spark plugs in my motorcycle. This spark plug is 2 pieces and the other 2 will use Iridium spark plugs.View Detail

Part number of spark plugs same as the spark plug that was installed from the factory of 2014 KTM 1190 Adventure R. I think it is necessary to change the spark plug when the motorcycle is 2 years old and up. Which I think NGK brand is the brand of spark plug that I'm confident.View Detail

This is a racing spark plug for the YZ250F 2018. We decided we would try a racing plug for a change to see if there was any difference in performance. Finding the correct plug was not super hard as I already have a bookmark for NGK website and that way it's easy. Webike's price for this part was very good value. A lot lower than I could source locally here in the UK. With some other parts in my basket and shipped by EMS all arrived in 5 days.EMS are good value, very fast in delivering and better than some other couriers. All the items in my order were packed individually by Webike warehouse and all nicely padded out in the box so nothing could get damaged in transit and fill any space with bubble wrap and air pockets so nothing can be bounced about in transit. All arrived at my door perfectly. Didn't take too long to fit, pretty straightforward, after all it's a spark plug. Take your time and you will be just fine. Only time will tell if it has better performacne than the stock plug. Very pleased, thank you Webike for all your hard work and dedication.View Detail
