Iridium Spark Plug
Plug electrodes conventionally have used nickel and Iridium. These were not pure metals, but alloys containing other metals. Depending on the composition of the alloy, the matrix material's properties can be maximized. Using the same approach, iridium is alloyed with rhodium. The rhodium layer covers the iridium, improving the properties of the iridium.
Smallest Diameter Excellent Durability Less fuel consumption
0.4mm diameter iridium center electrodes have an extremely small cooling effect, reducing non-firing and realizing assured ignitability.
By welding a platinum tip to the ground electrode, wear has been controlled to a significant extent in the plug. In addition to acceleration performance, the life and durability of this plug has been increased to that of a platinum plug.
Even during idling, when it is easy for ignition to degrade, the plug reduces mis-sparking and stabilizes idling speed. This results in a quieter engine and improved fuel consumption.

When the spark plug should be exchanged?
If the center electrode tip becomes worn out into a round shape, it is possible that the sparks produced are not as effective, resulting in the fuel-air mixture being ignited less steadily. If this happens, engine horsepower decreases fuel consumption becomes worse, and engine lifetime may be negatively affected; we recommend regular replacement of spark plugs.
Cars: 15,000 to 20,000km
Small Car(6600cc)s: 7,000 to 10,000km
Motorcycles: 3,000 to 5,000km
Installation Steps:
1. Use the correct wrench for the hex on the plug, and be careful not to damage the insulator.
2. When changing, make sure that the oil, etc. on the outside of the plug does not enter the engine interior.
3. When putting the plugs in, clean the engine side of the flange, and put in the plugs after making sure the gasket is in the flange.
4.Make sure the plugs are vertical, and tighten them by hand until they cannot be tightened any further.
Then, use a plug wrench to tighten them accurately to the torque or rotation angle showed in the chart below.
