Under high voltage, the air between the center electrode and the side electrode of the spark plug will rapidly undergo ionization, forming positively charged ions and negatively charged free electrons. When the voltage between the electrodes reaches a certain value, the number of ions and electrons in the gas increases like an avalanche, causing the air to lose its insulation, and the gap forms a discharge channel, resulting in "breakdown" phenomenon. At this point, the gas forms a luminous body, known as a "spark".

The replacement cycle of spark plugs is directly related to their material. The replacement cycle of nickel alloy spark plugs is 20000 to 30000 kilometers, nickel yttrium alloy spark plugs are 30000 kilometers, single platinum spark plugs are 40000 kilometers, double platinum spark plugs are 60000 kilometers, iridium spark plugs are 80000 kilometers, and platinum iridium alloy spark plugs can reach 100000 kilometers.
