How often should the spark plugs be replaced in a Sagitar 1.4T?

[OmarAnn]

The replacement interval for spark plugs in a Sagitar 1.4T primarily depends on the mileage. It is recommended to replace the spark plugs once every 40,000 to 60,000 kilometers. Spark plugs are a crucial component of the gasoline engine's ignition system. They introduce high voltage electricity into the combustion chamber and generate a spark by jumping the electrode gap, thereby igniting the combustible air-fuel mixture in the cylinder. Steps for replacing spark plugs: Open the hood, lift the engine's plastic cover, and remove the high-voltage distributor 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 thoroughly cleaned. 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 secure the cover.
