How often should the spark plugs of Wuling Hongguang S be replaced?

[LeKai]

Wuling Hongguang S spark plugs are recommended to be replaced every 40,000 kilometers. The spark plug, commonly known as the sparking plug, functions by discharging the pulsed high-voltage electricity sent from the high-voltage wire, breaking down the air between the two electrodes of the spark plug to generate an electric spark, thereby igniting the mixed gas in the cylinder. The types of spark plugs are as follows: 1. Standard spark plug: The insulator skirt is slightly recessed into the shell end face, with the side electrode outside the shell end face, and it is the most widely used type; 2. Projected insulator spark plug: The insulator skirt is longer, protruding outside the shell end face. It has the advantages of high heat absorption and good anti-fouling ability, and can be directly cooled by the intake air to lower the temperature, thus it is less likely to cause hot ignition, so it has a wide thermal adaptation range; 3. Fine electrode spark plug: Its electrode is very thin, featuring strong sparks and good ignition ability, ensuring quick and reliable engine start even in severe cold seasons, with a wide thermal range to meet various purposes; 4. Tapered seat spark plug: Its shell and threaded part are made conical, so it can maintain good sealing without a washer, thereby reducing the size of the spark plug, which is more beneficial for engine design; 5. Multi-electrode spark plug: Generally has two or more side electrodes, with the advantage of reliable ignition and no need for frequent gap adjustment, so it is often used in some gasoline engines where the electrode is prone to erosion and the spark plug gap cannot be adjusted frequently; 6. Surface gap spark plug: Also known as the surface discharge type, it is the coldest type of spark plug, with the gap between the center electrode and the shell end face being concentric.
