1 Answers
The replacement interval for the spark plugs of the Volkswagen EA888 engine is 20,000 kilometers. Spark plugs are crucial components of the gasoline engine's ignition system. They introduce high voltage into the combustion chamber and create a spark by jumping the electrode gap, thereby igniting the combustible air-fuel mixture in the cylinder. The main types include: standard spark plugs, projected insulator spark plugs, electrode spark plugs, seat spark plugs, pole 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 is recommended to follow the owner's manual. You can refer to the following standards for maintenance replacement: platinum spark plugs should be replaced every 40,000 kilometers, ordinary nickel alloy spark plugs every 20,000 kilometers, and iridium spark plugs every 60,000 to 80,000 kilometers.
