For the Mercedes-Benz S-Class, the typical spark plug replacement interval is around **60,000 to 100,000 kilometers** under normal conditions. However, considering Pakistan’s fuel quality and driving habits such as frequent stop-and-go traffic, short trips, and exposure to dust and pollution:

* **Inspect Spark Plugs More Frequently:** It’s wise to check spark plugs every 30,000 to 40,000 kilometers.
* **Use High-Quality Spark Plugs:** OEM o r reputable brand spark plugs help maintain optimal performance.
* **Regular Maintenance:** Combine spark plug inspection with regular servicing, including fuel system cleaning and air filter replacement.
* **Fuel Quality:** Use the best available fuel to reduce deposits that wear out spark plugs faster.
