[DelIker]

BMW X3 does not require spark plug replacement at 20,000 kilometers. The replacement interval for BMW X3 spark plugs is 40,000 kilometers. If spark plugs are not replaced for a long time, it can lead to various issues such as leakage in the vehicle's ignition system, increased fuel consumption, reduced power, and most importantly, difficulty in starting, affecting the normal use of the vehicle. Spark plug replacement interval: Under normal maintenance conditions, replacement is recommended at 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it is advisable 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, standard 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 engine's plastic cover, and remove the high-voltage 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 cleaned thoroughly. Place the new spark plug into the spark plug hole, hand-tighten it a few turns, and then use the socket to tighten it further. Reinstall the removed high-voltage wires in the order of the firing sequence and secure the cover.
