How often should the spark plugs of Golf 7 be replaced?

[ManuelLynn]

The spark plugs of Golf 7 should be replaced every 30,000 to 50,000 kilometers. The replacement interval may vary depending on the material of the spark plugs. Under normal maintenance conditions, they should be replaced after driving 40,000 to 60,000 kilometers. However, this may differ due to brand and engine variations, so it is recommended to follow the user manual. You can refer to the following standards 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, and remove the high-voltage wires. 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 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 according to the firing order, and then secure the cover.
