How often should the spark plugs of the Golf Sportsvan be replaced?

[LeilaniMarie]

The Golf Sportsvan uses original EA211 iridium-platinum spark plugs with a replacement interval of 60,000-80,000 kilometers. Spark plugs are crucial components in a gasoline engine's ignition system. They introduce high voltage electricity into the combustion chamber and generate sparks by jumping the electrode gap, thereby igniting the combustible air-fuel mixture in the cylinder. They mainly consist of a terminal nut, insulator, terminal screw, center electrode, side electrode, and shell. Replacement interval for spark plugs: Normally replaced after 40,000-60,000 kilometers under proper maintenance conditions. However, this may vary depending on the brand and engine type, so it's 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 60,000-80,000 kilometers.
