Features
photo It has a 90°V-groove in the tip of the center electrode.
photo The V-groove ensures that the spark is directed to the periphery of the electrodes.
The flame core is generated near the perimeter of the electrodes and grows.
Ignitability is improved because the electrodes are interfering less with the growth of the flame core.
