How many kilometers can the original spark plugs of Emgrand last?

[DelBrooke]

The original spark plugs of Emgrand are platinum spark plugs, with the model number Bosch YR6NI302, which can generally last for 40,000 kilometers. Spark plugs are crucial components of the gasoline engine ignition system. They introduce high voltage electricity into the combustion chamber and generate sparks by jumping the electrode gap, thereby igniting the combustible mixture in the cylinder. Replacement cycle for spark plugs: Under normal maintenance conditions, they should be replaced after driving 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine, so it is recommended to follow the user manual. You can refer to the following standards for maintenance replacement: platinum spark plugs should be replaced at 40,000 kilometers, ordinary nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers.
