How many kilometers should the spark plugs of Haval H6 be replaced?

[MayaLee]

Haval H6 spark plugs should be replaced every 18 months or 18,000 kilometers, whichever comes first. The original spark plugs for Haval H6 use the Champion RC8PYCBX single platinum model. Under normal maintenance conditions, spark plugs 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 referred to for maintenance and 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 for 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 further. Install the removed high-voltage distributor wires according to the firing order and secure the cover.
