How often should the original spark plugs of Sagitar 1.6 be replaced?
2 Answers
The replacement interval for the original spark plugs of the Sagitar 1.6 mainly depends on the mileage driven. The spark plugs should be replaced 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 plastic cover of the engine, and remove the high-voltage ignition 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 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 removed high-voltage ignition wires according to the firing order, and then secure the cover.
My Sagitar 1.6 has been running for six or seven years now, and the replacement interval for the original spark plugs really depends on how you drive it. For ordinary nickel alloy ones, the manufacturer recommends changing them every 30,000 km. Since I do a lot of highway driving, mine lasted until 40,000 km, but during the last maintenance, the mechanic said the electrode gap had worn too large. If you often get stuck in city traffic or use lower-quality fuel, you might need to consider replacing them at around 25,000 km. Otherwise, cold starts can become shaky, and once I even felt like something was jamming when I pressed the accelerator. However, the newer double platinum models can last over 60,000 km. If you're going to replace them, I strongly recommend upgrading directly.
