How Often Should Standard Spark Plugs Be Replaced?

[Jordan]

Standard spark plugs should be replaced every 30,000 kilometers, platinum spark plugs around 60,000 kilometers, and iridium spark plugs around 80,000 kilometers. The replacement cycle varies due to differences in car brands and the types of spark plugs used, so replacement should be based on actual conditions. Below is some relevant information about spark plugs: 1. The gap between the electrodes of a spark plug greatly affects its performance. If the gap is too small, the spark will be weak and prone to carbon buildup and leakage. If the gap is too large, the required breakdown voltage increases, making the engine harder to start and more likely to misfire at high speeds. 2. Spark plugs, commonly known as "fire mouths," mainly include standard spark plugs, insulator projection spark plugs, electrode spark plugs, seat-type spark plugs, pole-type spark plugs, and surface-gap spark plugs.
