The recommended replacement interval for the original spark plugs of the Volkswagen Tiguan is 40,000 to 60,000 kilometers, using NGK double platinum spark plugs with the model number PFR7S8EG. Spark plug replacement cycle: Under normal maintenance conditions, replacement is required after driving 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it is advisable to refer to 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. Spark plugs are a crucial component of the gasoline engine's ignition system. They introduce high voltage electricity into the combustion chamber and create a spark by jumping the electrode gap, thereby igniting the combustible mixture in the cylinder. The main types of spark plugs 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.
I remember driving the Volkswagen Tiguan for so many years, and changing spark plugs really depends on the specific situation. Generally speaking, the original ordinary spark plugs need to be replaced every 20,000 to 30,000 kilometers. If you switch to platinum or iridium spark plugs, they can last 40,000 to 60,000 kilometers. My colleague didn’t change his spark plugs at 30,000 kilometers, and suddenly his fuel consumption skyrocketed, and the acceleration became jerky. Upon inspection, it turned out the spark plug electrodes were completely worn out. However, you can’t just rely on mileage alone. For example, I often drive in city traffic with frequent stops and starts, which wears out the spark plugs faster, so I check them every 20,000 kilometers. If you have trouble starting the car in cold northern winters, it might also be due to worn-out spark plugs. It’s best to have the mechanic check the spark plugs for wear during every maintenance service.
