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.

The working principle of a spark plug is that the insulation skirt of a standard spark plug is slightly shrunk into the end face of the housing, and the side electrode is outside the end face of the housing, making it the most widely used type. The insulation skirt of the edge protruding spark plug is longer and protrudes beyond the end face of the housing. It has the advantages of large heat absorption and good anti fouling ability, and can be directly cooled by the intake air to lower the temperature, so it is not easy to cause hot ignition, so the thermal adaptation range is wide.
