The shape of the shell forming the outer electrode and special termination of the insulator tip provide extremely long surface spark discharge. The spark discharge is always in the point with the highest fuel concentration. The combustion speed linked with knocking sensors of high tech engines allows for increasing engine performance. The replacement interval is 35,000km.

Two auxiliary Titanium Oxide Electrodes. Applied by a patented technology upon the insulator nose allow for simultaneous discharge of two surface and one air gap spark at one impulse of the ignition system. The number of sparks as well as increased engine performance. The replacement interval is 20,000km

Silver fine wire centre electrode, with tapered ground electrode. Higher insulation parameters from special high dielectric strength insulator and resistance to fouling facilitates ignition of hard to ignite fuels such as LPG. The replacement interval is 30,000km.
