How often should the spark plugs of the new Sagitar 1.4T be replaced?

The spark plugs of the new Sagitar 1.4T generally need to be replaced at 20,000 to 30,000 kilometers. Under normal maintenance conditions, car spark plugs should be replaced after 40,000 to 60,000 kilometers of driving. However, this may vary depending on the brand and engine, so it is recommended to follow the user manual. The following standards can be used as a reference 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 each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. When removing them, check for external debris like leaves or dust and ensure they are thoroughly cleaned. 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 plate.

I've been driving my new Sagitar 1.4T for almost five years now. The spark plugs are typically best replaced at 60,000 kilometers, as suggested by the technician during my last maintenance visit at the 4S shop. They mentioned that the original spark plugs can last up to 80,000 kilometers, but if you frequently encounter city traffic jams with constant starts and stops, the wear accelerates, making earlier replacement advisable. After changing them at 60,000 kilometers, I noticed the car starts quicker, fuel consumption has stabilized, and those minor vibrations are gone. Each spark plug costs around a hundred yuan, with a full set replacement totaling a few hundred. Delaying replacement might lead to poor engine ignition, increased fuel consumption, or even malfunctions, potentially requiring major repairs costing thousands—definitely not worth it. Regularly changing spark plugs is a small maintenance task that contributes to overall peace of mind with your vehicle.

Spark plugs are essential components for engine ignition. From what I understand, the new Sagitar 1.4T should have its spark plugs replaced every 60,000 to 80,000 kilometers for safety. Delaying replacement leads to aging spark plugs, reduced ignition efficiency, a sharp increase in fuel consumption, and rough engine starts. In worse cases, it may damage other components like the ignition coil. My routine is to have them inspected every two to three years or every 40,000 kilometers, with replacement recommendations listed on the maintenance sheet. Iridium spark plugs are more durable, but long-term neglect of cleaning can still lead to carbon buildup, affecting performance. Simple maintenance can prevent major issues.

The 1.4T engine of the new Sagitar recommends replacing spark plugs every 60,000-80,000 kilometers. If there's frequent city traffic congestion, consider replacing them earlier. Worn spark plugs can easily cause ignition failures and increase fuel consumption. The most worry-free approach is to check the spark plug condition during regular maintenance.
