When to Replace the Spark Plugs for Wuling Hongguang S?
2 Answers
It is recommended to replace the spark plugs for Wuling Hongguang S every 40,000 kilometers. Below is an introduction to spark plugs: 1. The main components of a spark plug are the insulator, shell, terminal stud, and electrodes. The spark plug electrodes include the center electrode and the side electrode, with a spark gap between them. 2. The size of the gap directly affects the engine's startup, power, operational stability, and fuel efficiency. A reasonable gap is related to the ignition voltage. 3. The electrode material must have excellent resistance to electrical erosion and corrosion, as well as good thermal conductivity. Between the center electrode and the terminal stud is a conductive glass sealant, which must be capable of conducting electricity, withstanding the high pressure of combustion mixture, and ensuring its sealing performance.
I've been driving a Wuling Hongguang S, and the spark plug replacement interval depends on your driving habits. If you're like me, often stuck in city traffic with frequent stops and starts, it's recommended to change them every 30,000 to 40,000 kilometers because poor road conditions accelerate spark plug wear. I changed mine at 35,000 kilometers last time, and the ignition became smoother while fuel consumption dropped by about 10%. Don't wait until the car has difficulty starting to address it, otherwise the engine will start shaking and repairs will cost more. During regular maintenance, ask the mechanic to pull them out and check if the electrodes are eroded or have excessive carbon buildup. The manual might have recommended values, but in practice, base it on the actual vehicle condition. A little tip: After replacement, take a short test drive to listen for even ignition sounds to ensure everything is working properly.
