How often should the spark plugs be replaced on a Buick Excelle?

[LeGabriel]

Buick Excelle's spark plugs should be replaced every 40,000 kilometers. Spark plugs utilize high-voltage discharge to break down the air between electrodes, generating an electric spark to ignite the combustible air-fuel mixture in the combustion chamber, thereby maintaining engine operation. When removing or installing spark plugs, care must be taken to prevent dust from entering the cylinder. The surrounding area should be cleaned thoroughly before removing the spark plugs. The Buick Excelle is a compact car under SAIC-GM Buick, with dimensions of 4609mm in length, 1798mm in width, and 1486mm in height, and a wheelbase of 2640mm. The vehicle is equipped with safety features such as SBZA Side Blind Zone Alert, TPMS Intelligent Tire Pressure Monitoring System, rear parking sensors, Bosch ESP9.1 Electronic Stability Control System, laser-brazed integrated roof, and auto-dimming rearview mirror.
