Do BMWs Need Spark Plug Replacement After 20,000 Kilometers?

[CalebRose]

BMWs do not necessarily require spark plug replacement at 20,000 kilometers; they can be replaced every 40,000 kilometers. Spark Plug Replacement Interval: 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 type. It is recommended to follow the owner's manual. The following standards can be referenced for maintenance replacement: platinum spark plugs should be replaced at 40,000 kilometers, standard nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers. Spark Plug Replacement Steps: Open the hood, lift the engine's plastic cover, and remove the high-voltage ignition wires. Mark each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing them, check for any external debris like leaves or dust and ensure they are thoroughly cleaned. Insert the new spark plugs into the spark plug holes, hand-tighten them a few turns, and then use the socket to tighten them further. Reinstall the high-voltage ignition wires according to the firing order, and then secure the cover.
