How often should the spark plugs be replaced in the Lingpai?

[Leah]

Lingpai requires spark plug replacement every two years or 40,000 kilometers. Spark plugs, commonly known as sparkers, function by discharging the pulsed high-voltage electricity delivered through the high-tension leads (sparker wires), breaking down the air between the two electrodes to generate an electric spark, thereby igniting the air-fuel mixture in the cylinder. The Lingpai is a 4-door, 5-seater sedan with dimensions of 4756mm in length, 1804mm in width, and 1509mm in height, featuring a wheelbase of 2730mm. This vehicle is equipped with a naturally aspirated intake system and a 1.5L L4 engine, delivering a maximum horsepower of 109ps, a maximum torque of 134Nm, and a maximum power output of 80kW.
