How Long Does an Iridium Spark Plug Last?

[MacRemington]

Iridium spark plugs can last between 60,000 to 100,000 kilometers, which is at least twice as long as standard spark plugs. Iridium spark plugs refer to automotive spark plugs whose electrodes are made from the precious metal iridium. Spark plugs are devices that ignite the mixture of gasoline and air entering the engine for combustion, serving as the terminal component of the engine's ignition system. Iridium is an extremely hard precious metal capable of withstanding temperatures up to 2,000 degrees Celsius. It boasts excellent corrosion and wear resistance, and the use of iridium in spark plug electrodes leverages these properties. Iridium spark plugs offer significantly stronger ignition capabilities compared to standard nickel-alloy spark plugs.
