How often should the spark plugs of the Touran be replaced?

The spark plugs of the Volkswagen Touran should be replaced every 60,000 to 70,000 kilometers. Under normal maintenance conditions, car spark plugs are typically replaced after 40,000 to 60,000 kilometers of driving. However, this may vary depending on the brand and engine type, so it is recommended to follow the instructions in the owner's manual. The following standards can be referenced for maintenance and replacement: platinum spark plugs should be replaced at 40,000 kilometers, standard 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 ignition 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 ignition wires in the correct firing order and secure the cover plate.

My old Touran has been running for almost ten years, and I've changed the spark plugs three times. Generally, 4S shops recommend checking them every 20,000 kilometers and replacing them around 30,000 kilometers. But it also depends on the material of your spark plugs. Ordinary nickel alloy ones do need more frequent replacement, while upgrading to platinum or iridium ones can last 40,000 to 60,000 kilometers. Last time my car shook during cold starts, the mechanic found two spark plugs with yellowed ceramic bodies and the electrode gap almost as thick as a coin. Don’t make the same mistake of delaying too long like I did. Worn-out spark plugs not only waste fuel but can also severely damage the catalytic converter, making repairs painfully expensive.

Having seen numerous spark plug issues with the Touran in the repair shop, an interesting phenomenon was observed: vehicles used predominantly for short city trips tend to accumulate more carbon deposits than those frequently driven on highways. If you've misplaced the maintenance manual, don't panic—just watch for these telltale signs: the steering wheel vibrates like a massage chair at idle, the throttle feels sluggish when overtaking, and fuel consumption suddenly increases by 1-2 points—it's time to check the spark plugs. When replacing them, we use a torque wrench for precise tightening and apply insulating silicone grease for better moisture resistance during the rainy season. After the replacement, you'll feel the throttle as light and responsive as after a major service.

Spark plugs are essentially the lighters of an engine, and the EA211 or EA888 engines in older Tourans are particularly sensitive to ignition. Recently, while helping a friend inspect his 2018 Touran, we found that the spark plugs, which hadn't been replaced in 70,000 kilometers, were almost completely worn down at the electrodes. It's recommended to check them every third maintenance: just disconnect the high-voltage coil wiring and use a 16mm long socket to remove them. The newer platinum spark plugs last longer, but don't be fooled by claims of being lifetime maintenance-free—spark plugs in turbocharged models wear out much faster than in naturally aspirated ones. Remember: if the throttle feels heavier, don't push it—just replace them when needed.
