How Often Should Volkswagen Spark Plugs Be Replaced?
1 Answers
Volkswagen spark plug replacement intervals are as follows: Original spark plugs should typically be replaced every 20,000 to 30,000 kilometers under normal conditions. For turbocharged engines, spark plugs require more frequent replacement. Iridium and platinum spark plugs can last 60,000 to 80,000 kilometers before needing replacement. Different spark plugs have their own replacement cycles because electrode materials determine their service life - your vehicle's manual specifies the exact replacement mileage. As a critical ignition component that operates under extreme high-temperature and high-pressure conditions, spark plugs perform the vital function of igniting the air-fuel mixture in the combustion chamber. Their condition significantly impacts fuel efficiency, engine performance, and overall driving smoothness.
