How Often Should BMW Spark Plugs Be Replaced?
1 Answers
BMW spark plugs generally need to be replaced every two years or 40,000 kilometers. If spark plugs are not replaced for a long time, it can cause various issues such as leakage in the vehicle's ignition system, increased fuel consumption, reduced power, and most importantly, difficulty in ignition, which affects the normal operation of the vehicle. 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, so it is recommended to follow the user manual. The following standards can be used as a reference 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 and lift the plastic cover of the engine. Remove the high-voltage wires and 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 cleaned 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. Reinstall the high-voltage wires in the correct firing order and secure the cover.
