The diameter of the center electrode is very fine.
The tip of ground electrode is taper cut.
It produces sparks very easily and has excellent ignitability.
Better performance is achieved with improved starting, acceleration, and idling stability, as well as fuel-efficiency.
 Combustion pressure test
The Iridium IX spark plug has less dispersion than a conventional spark plug, allowing it to maintain stable performance.
Acceleration test
Increased power in the middle rpm range provides improved acceleration performance.

Since the center electrode is very fine, the flame core grows larger.
Moreover, the tip of ground electrode is taper cut.

Example of part number of IX spark plug
|
Ignitability is improved because the quenching action of the spark plug electrode is diminished. Please refer to Question 16.
A space has been provided in the tip of the insulator where accumulated carbon is burnt off by minute electrical discharge, preventing a decline in insulating performance. |
