Replacement Interval for Touran Spark Plugs?
2 Answers
The replacement interval for Touran spark plugs is 25,000 kilometers or 18 months. Below are precautions for replacing Touran spark plugs: Avoid prolonged carbon buildup neglect: During usage, normal carbon deposits will form on the electrodes and skirt insulator of spark plugs. If these deposits are not cleaned over time, they will accumulate excessively, eventually leading to electrode leakage or even failure to spark. Therefore, carbon deposits should be cleaned regularly, not only when the spark plugs stop functioning. Avoid prolonged usage: There are various models of spark plugs, each with its own economic lifespan. Continuing to use spark plugs beyond this lifespan can negatively impact engine performance and fuel efficiency. Research indicates that prolonged use causes the central electrode tip to become rounded and the side electrode to develop a concave shape, increasing the electrode gap and making discharge difficult, which affects normal engine operation. Avoid improper cleaning: When applying silver spray or performing other engine maintenance, neglecting the cleanliness of the spark plug exterior can lead to leakage due to dirt. For cleaning, avoid using sandpaper or metal scrapers for convenience, as these can damage the ceramic body. Instead, soak the spark plugs in gasoline and clean them with a brush to ensure the ceramic exterior remains undamaged.
I've been driving a Volkswagen Touran for several years, and spark plug replacement is definitely not something to be taken lightly. Generally, manufacturers recommend replacing them every 3 to 5 years or every 60,000 to 80,000 kilometers, depending on your driving habits. For example, since I usually commute in the city with frequent traffic jams and constant engine start-stop cycles, the spark plugs wear out faster, so I have them checked every 40,000 kilometers. If you notice difficulty starting the car, a sudden increase in fuel consumption, or rough idling, those are clear signs it's time for a replacement. Even if you're not familiar with car repairs, you can easily get it done at a 4S shop or a reliable repair shop—the parts aren't expensive, costing just around a hundred yuan. Just make sure to choose the right model when replacing them. For Volkswagen cars, NGK or Bosch spark plugs are the best options—don't go for cheap, off-brand ones to save money. Proper maintenance ensures smoother performance and a longer lifespan for your car. Think of it like a health check-up—doing it regularly helps avoid major problems.
