UNIQUE SPARK PLUG MADE BY APPLICATION OF PATENTED TECHNOLOGY
Spark plugs with two auxiliary electrodes on the surface of the insulator tip.
Three sparks in series at one impulse of the ignition system with a possibility of spark-over around the full circumference (360°).
Replacement interval: see table below.
Auxiliary electrodes deposited on insulator tip with special patented technology lend the spark plugs unique properties, particularly the balancing of the individual indicated mean pressures and shift of their average toward the upper limit, which in the final consequence increases engine power.
The special spark gap protrudes deep into combustion chamber, thanks to which the mixture is perfectly ignited in the combustion chamber.
The Premium ZC/ZS range spark plugs require powerful ignition systems, perfect blending of mixture and utilisation of the engines in the high-rpm zone.
The Premium ZC spark plug has a centre electrode with copper core and the Premium ZS has a silver centre electrode.
