What are the consequences of using incorrect spark plug models?

[JuneLee]

The consequences of using incorrect spark plug models include engine knocking and overheating, which can lead to unstable engine speed or weak driving performance. The service life of resistor spark plugs is 20,000 kilometers, platinum spark plugs last for 40,000 kilometers, and iridium spark plugs can reach 60,000 to 80,000 kilometers. If you notice increased fuel consumption in your vehicle, consider replacing the spark plugs. In spark plug standards, the heat value is typically used to characterize the thermal properties of spark plugs. The heat value of a spark plug indicates the balance between heat absorption and dissipation at the insulator skirt. A higher heat value means stronger heat absorption and dissipation balance capability. Therefore, hot-type spark plugs have lower heat values, while cold-type spark plugs have higher heat values.
