We increase power by twisting spark plugs - how is it ?!
If in old cars the candles changed literally in five minutes, then in modern cars for this sometimes you need to disassemble a half-motor. Therefore, ideally, the candle should serve about the same as the motor itself. But ordinary steel and even chromium-nickel alloys gradually burn out due to spark erosion due to spark discharge. In addition, during the operation of the candle, a deposit forms on it, sharply worsening its performance.
The best indicators in terms of refractoriness are possessed by platinum group metals - iridium, platinum, yttrium. In this case, the advantage of iridium is its good thermal conductivity, which is almost an order of magnitude higher than that of chromium-nickel alloys. For a candle, this is very important, since high thermal conductivity reduces the temperature of the electrode. However, such metals are very expensive. But iridium allows you to make the electrodes extremely tiny. For example, in Japanese Denso Iridium the thickness of the central electrode is only 0.4 mm, while in a conventional candle based on a nickel-chromium alloy it is about 2.5 mm.

Thinking about HBO? Do not forget about special candles! However, saving metal is not the main advantage of thin electrodes.
Just as a lightning strike affects lonely trees, masts, and, of course, lightning rods, thin candle electrodes can increase the discharge energy, which has a positive effect on power, efficiency and ecology.
Our tests showed that even in comparison with high-quality, but "thick" candles, their "thin" colleagues are able to improve efficiency by 6-7%.
In addition, thin electrodes allow candles to work confidently during emergency undervoltage in the electrical system.
As for the resource, 100, 000 km is a very real value for “thin people”. Their only drawback is a higher price compared to "ordinary" candles.
