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

Geely Emgrand GS's spark plugs have a lifespan of 20,000 kilometers, so they need to be replaced every 20,000 kilometers. Spark plug replacement cycle: 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. The following standards can be used as a reference 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. Steps for replacing spark plugs: Open the hood, lift the plastic cover of the engine, remove the high-voltage distributor wires, and mark the position of each cylinder to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. When removing them, check if there are any leaves, dust, etc., on the outside and make sure to clean them thoroughly. Place the new spark plugs into the spark plug holes, hand-tighten them a few turns, and then use the socket to tighten them. Install the removed high-voltage distributor wires in the order of ignition, and then snap the cover back on.
Having driven the Emgrand GS for several years, I believe spark plug replacement should be based on actual conditions. Generally, it's recommended to change them every 30,000 to 40,000 kilometers, or approximately every two years. Once my car experienced unstable idling and insufficient power during acceleration, and the inspection revealed severely carbon-fouled spark plugs. Now I regularly have them checked during maintenance, and platinum spark plugs offer better durability, lasting up to 60,000 kilometers. Don't forget, frequent city driving in congested traffic accelerates spark plug wear. After replacement, the engine ignites more precisely, fuel consumption slightly decreases, and driving becomes smoother. Actually, you can perform a simple spark plug check yourself by pulling them out to examine the electrode gap - if it exceeds 0.9mm, it's time for replacement. Don't wait until they completely fail before fixing them.
