How often should the spark plugs of Audi Q2L be replaced?

[Jenkins]

Audi Q2L spark plug replacement cycle: Under normal maintenance conditions, they should be replaced after driving 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type. 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. How spark plugs work: The ground electrode of the spark plug is connected to the metal shell, which is then connected to the engine block via the cylinder head threads. The insulator primarily serves to isolate the metal shell from the central electrode. The terminal nut is the part of the spark plug that contacts the high-voltage coil. When current passes through the terminal nut and the central electrode, it ionizes the medium between the central electrode and the ground electrode, generating a spark to ignite the air-fuel mixture in the cylinder.
