Does the Audi Q5 need to replace spark plugs at 20,000 kilometers?

[DelLeo]

Audi Q5 recommends replacing spark plugs every 20,000 kilometers. Spark plugs are crucial components in a gasoline engine's ignition system. They introduce high voltage electricity into the combustion chamber and create a spark by jumping the electrode gap, thereby igniting the combustible mixture in the cylinder. Steps for replacing spark plugs: Open the hood, lift the plastic cover of the engine, remove the high-voltage distributor 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 external debris like leaves or dust and ensure everything is 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 distributor wires according to the firing order, and then secure the cover.
