How often should the original spark plugs of the Leiling be replaced?

[DelilahLee]

Leiling's original spark plugs should be replaced every two years or 40,000 kilometers. Spark plugs are a crucial component of a gasoline engine's ignition system, as they introduce high voltage into the combustion chamber and generate sparks by jumping the electrode gap, thereby igniting the combustible mixture in the cylinder. Taking the 2021 Leiling as an example, its body dimensions are: length 4640mm, width 1780mm, height 1455mm, with a wheelbase of 2700mm and a fuel tank capacity of 50 liters. The 2021 Leiling is equipped with a 1.2T turbocharged engine, delivering a maximum horsepower of 116PS and a maximum power of 85kW, paired with a CVT continuously variable transmission. It features a front suspension type of MacPherson independent suspension and a rear suspension type of E-type multi-link independent suspension.
