How many kilometers does the Mercedes-Benz E260 need to replace the spark plugs?

[MacHailey]

The replacement interval for spark plugs in the Mercedes-Benz E260 is 60,000-80,000 kilometers, and it uses NGK iridium spark plugs. Spark plugs are a crucial component of the gasoline engine ignition system. 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 typically 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 every 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it's recommended to follow the owner's manual. You can refer to the following maintenance standards for 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 60,000-80,000 kilometers.
