The spark plugs of the Vision X6 should be replaced every 20,000 kilometers. Under normal conditions, car spark plugs are typically replaced after traveling 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it is recommended to follow the user manual. The following standards can be referred to 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 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 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 distributor wires according to the ignition sequence and secure the cover plate.

Generally speaking, the spark plugs of the Vision X6 are recommended to be replaced every 30,000 to 40,000 kilometers. Speaking from a repair perspective, these are crucial for engine ignition. When worn out, unstable ignition can cause the car to shake and accelerate poorly, and in severe cases, fuel consumption can skyrocket or even damage the catalytic converter. I've seen many car owners delay replacement until over 50,000 kilometers, only to face difficult starts and costly engine repairs. So it's best to follow the maintenance manual for regular checks, such as every two years or 30,000 kilometers, depending on your driving habits—replace them earlier if you frequently encounter city traffic jams. Ensuring the health of the ignition system can extend the overall lifespan of the vehicle, so don't underestimate this component.

The original spark plugs for the Vision X6 are nickel alloy type, with a lifespan of approximately 30,000-40,000 kilometers. If you upgrade to higher-grade materials like platinum or iridium, they may last 50,000-60,000 kilometers, but they are slightly more expensive and require compatibility with your vehicle model. Worn spark plugs can affect ignition energy; when the electrode gap becomes too large, performance declines, fuel consumption increases, and starting becomes sluggish. It's safest to inspect them every 30,000 kilometers. You can visually check them yourself, but the removal location might be tight, so it's recommended to have a professional shop handle it to prevent damage to the wiring harness.

The replacement interval for spark plugs is crucial for driving safety. The Vision X6 should have its spark plugs replaced every 30,000 to 40,000 kilometers. Ignition system failures may cause engine misfires, leading to sudden loss of power while driving at high speeds, which increases the risk of accidents, especially in rainy or snowy weather. I have encountered cases of engine stalling caused by aged spark plugs, resulting in high repair costs and wasted time. It is essential to follow the maintenance manual's recommendations, inspecting them every 2-3 years. Timely replacement ensures stable power output and avoids unnecessary safety hazards.
