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

[StMadison]

Under normal circumstances, it is recommended to replace the spark plugs of the Wuling Hongguang S every 40,000 kilometers. Spark plugs, commonly known as spark electrodes, function 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 main types of spark plugs include standard spark plugs, insulator-protruding spark plugs, electrode-type spark plugs, seat-type spark plugs, pole-type spark plugs, and surface-gap spark plugs. The Wuling Hongguang S is a crossover independently developed product between commercial vehicles and passenger vehicles launched by SAIC-GM-Wuling based on the Wuling Hongguang model. The large-sized roof luggage rack configured on the top of the vehicle further highlights the multifunctional characteristics of the compact business vehicle. The integrated curved spoiler at the rear of the vehicle effectively reduces airflow during driving and provides appropriate downforce. The dynamic waistline and wedge-shaped skirt line on the side give the vehicle a more layered and streamlined appearance.
