How many kilometers should the spark plugs of the Sagitar 1.6 be replaced?

[SanJohnny]

The spark plugs of the Sagitar 1.6 should be replaced every 40,000 to 60,000 kilometers. Spark plugs are a crucial component of the gasoline engine's ignition system. They introduce high voltage 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 engine hood, lift the plastic cover of the engine, and remove the high-voltage distributor wires. Mark the position of each cylinder 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 everything is 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 distributor wires in the firing order and secure the cover.
