How often should the spark plugs of the New Emgrand be replaced?

[Josephine]

The spark plugs of the New Emgrand should be replaced every 20,000 kilometers. Spark plugs are a crucial component of gasoline engines, determining whether the engine can ignite properly. When the ignition coil, following the engine's firing order, delivers a pulsed voltage to the spark plug via the high-voltage wire, the spark plug uses this voltage to create an electric spark by ionizing the air between its two electrodes, thereby igniting the combustible air-fuel mixture in the engine cylinder. The New Emgrand is a compact model under Geely, with body dimensions of 4632mm in length, 1789mm in width, and 1470mm in height, and a wheelbase of 2650mm. In terms of power, the vehicle is equipped with a 1.5-liter inline 4-cylinder naturally aspirated engine, delivering a maximum power of 80KW and a maximum torque of 140NM, paired with either a 5-speed manual transmission or a CVT continuously variable transmission.
