The electrode wears from the locations that discharge easily with spark discharge.
In particular, since the center electrode reaches high temperatures, it oxidizes and wears. The amount of electrode wear varies with the electrode material melting point, strength, hardness, etc. In order to reduce the amount of this wear, nickel alloys, platinum, iridium, and other such materials are used for the electrodes and service lives are also extended with fine electrodes.
Also, the wear varies with the engine type and usage conditions, but for normal plugs, it is approximately in the range of 0.10-0.15mm for each 10,000km driven.

Continuing to use a spark plug with worn electrodes puts stress on the ignition coil and can shorten its life.
Please replace spark plugs sooner rather than later.
Beware of only using your vehicle for short trips or slow driving!
This can lead to carbon fouling or oil fouling.

The required voltage (the voltage required to discharge across the gap) rises in proportion to the distance driven.
This rise in the required voltage is large until the sharp section at the end of the center electrode is worn round to some degree (about 4,000km). After that, the main factor is the enlargement of the gap due to electrode wear and the rise in the required voltage is smaller.

Regarding the spark plug replacement timing

The electrode progressively wears, causing the spark gap to increase, along with the increasing number of spark discharges. When the gap exceeds a certain limit, the sparking performance deteriorates, which may prevent stable ignition of the gas mixture. When this happens, the horsepower of the engine falls, the fuel economy deteriorates and also the quality of the exhaust gas is adversely affected, so it is necssary to replace the plugs.

[/vc_column_text][vc_single_image image=”9029″ img_size=”full” alignment=”center”][vc_column_text animation_delay=”0″]The physical service life for a spark plug can be thought of as the number of kilometers driven until the spark plug begins to misfire. Misfiring causes not only wastage of fuel, but also irregular engine vibration and output drop. In particular, for vehicles with emissions controls, misfiring can damage the catalytic converter, so using a spark plug all the way to the end of its physical service life is inexpedient economically.
Therefore, as the economical replacement interval, replacement after the number of kilometers in the figure above is recommended. (However, 100,000km for platinum spark plugs.)[/vc_column_text][/vc_column_inner][/vc_row_inner][vc_column_text animation_delay=”0″]

Lifespan of iridium spark plugs
