[Features, Structure]
D-Shape outer electrode with new material and center electrode with Ruthenium!
As a dedicated Spark plug for two-wheeled vehicles, we have developed a variety of Spark plug performance requirements (acceleration, durability, dirt resistance, fuel economy, start-up, etc.). ) with improved.
The D-shaped outer electrode (D-Shape outer electrode) and the Ruthenium blended center electrode provide outstanding combustion efficiency..
D-Shape outer electrode is shaped to prevent obstructing the flow of the mixture! It leads the mixture to the spark gap efficiently..
The D-Shape outer electrode is designed to prevent the flame from spreading. Ideal combustion close to spherical shape is realized..

About the shape of the plug terminal] ● Select the shape of the terminal (terminal) that matches the installation side of the engine and plug cord.. There are four types of plug terminals:'integrated type', 'separated type', 'screw type' or 'punch rivet type'. 'Integrated type' and 'punch rivet type' are mainly used for 4-wheel vehicles, 'screw type' is used for motorcycles, and 'separated type' is used for both. Also, though the terminal of 'separate type' will go off, you cannot remove ones of 'integrated type' or 'punch rivet type'. You will break the terminal if you force to do so. If you are to use 'separate type' as 'screw type', remove the terminal nut. If you are using with the terminal nut, make sure that it is not loosened, and if is, retighten it lightly using a plier.

[NGKPlug Features]

- It's a super "wide range" plug -

Its central electrode has copper core till its tip and releases vast amount of heat quickly. This provides an ultra wide range of plug that is resistant to burning and smoldering..

Comparing the thermal characteristics of copper-cored and non-copper-cored plug, copper-cored plug has excellent thermal characteristics and stain resistance and has a wide thermal range..

Thermal value of Plug

- New ceramics' high alumina porcelain is used for the insulator -

Excellent insulation at high temperature and reliable sparking. * Excellent in thermal conductivity and prevents over burning. * Durable to heat shock (rapid heating or cooling), and mechanically strong.

- Strong structure and highly airtight

Excellent airtightness and structural strength as the insulator and the main bracket are bonded by special powder..

The electrode is made of special Nickel alloy gold and has excellent durability..

- Corrugations in the insulator ensure insulation and prevent FLUSHOver.

High voltage is constantly applied between the terminal and the main body bracket at the time of park.. High voltages tend to leak along the surface of the insulator, and the higher the required voltage between the spark gaps, the more likely it is that FLUSHOver will occur.. In order to prevent FLUSHOver, insulator corrugation (folds) is provided to increase the insulator surface distance between the terminal←→and the main bracket to ensure insulation and prevent FLUSHOver..

What is FLUSHOver...

It is to park between the Terminal and the subject Bracket as shown in the picture.
