How many kilometers should the spark plugs of the Tayron be replaced?

The replacement cycle for Tayron spark plugs is 20,000 kilometers or 2 years, whichever comes first. The original equipment uses Bosch and NGK brand spark plugs. Under normal maintenance conditions, spark plugs should be replaced when the car has traveled 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine, so it is 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 to 80,000 kilometers. Spark plugs are an important 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 mixture in the cylinder. The main types of spark plugs include: standard spark plugs, insulator-protruding spark plugs, electrode spark plugs, seat-type spark plugs, pole-type spark plugs, and surface-gap spark plugs.
My Volkswagen Tayron has been running for over 5 years, and I replaced the first set of spark plugs at 30,000 kilometers. Although the 4S shop recommends inspection every 20,000 kilometers, practical experience shows that standard nickel alloy spark plugs actually last between 20,000 to 40,000 kilometers. The most crucial factor is observing the vehicle's performance - symptoms like engine shaking during cold starts or sudden increases in fuel consumption are clear warning signs. Once during a highway drive, I experienced slight engine misfiring; when the repair shop opened it up, they found two spark plugs with completely worn-out electrodes. Later, I switched to iridium spark plugs, and the mechanic said they could last 60,000 to 80,000 kilometers. For urban commuters, I suggest having technicians inspect the spark plugs with a borescope during the 40,000-kilometer maintenance, especially since spark plugs wear out faster in carbon-heavy environments. Using 95-octane fuel regularly can also extend the ignition system's lifespan.
