How many kilometers should the spark plugs be replaced for Mercedes-Benz e260?

[DiColton]

The replacement interval for spark plugs in the Mercedes-Benz e260 is 60,000 to 80,000 kilometers, using NGK iridium spark plugs. Spark plugs are a crucial component of the ignition system in gasoline engines. They introduce high-voltage electricity into the combustion chamber and create a spark by jumping the electrode gap, thereby igniting the combustible air-fuel mixture in the cylinder. Spark plugs are generally installed on the side or top of the engine. The main types include: standard spark plugs, extended insulator spark plugs, electrode-type spark plugs, seat-type spark plugs, pole-type spark plugs, and surface-gap spark plugs. Replacement interval for spark plugs: Under normal maintenance conditions, they should be replaced after driving 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine, so it is recommended to follow the user manual. You can refer to the following standards for maintenance 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.
