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

[Ruby]

Emgrand's original spark plugs should be replaced every 80,000 to 100,000 kilometers. Spark plugs are a crucial component of the gasoline engine's ignition system. They introduce high voltage into the combustion chamber and generate a spark by jumping the electrode gap, thereby igniting the combustible air-fuel mixture in the cylinder. The key part of a spark plug is the insulator. If the insulator fails, the high voltage will "take a shortcut" and bypass the electrodes to ground, resulting in no spark. The Emgrand is a car under the Geely brand, which is a subsidiary of Geely Auto. The new Emgrand is equipped with a 1.3T GeTec DVVT turbocharged engine and features front-wheel drive.
