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.
The replacement interval for the Audi Q2L's spark plugs is actually quite flexible. When I drove this car myself, I also referred to the manual's recommendation, which is generally every 30,000 to 60,000 kilometers. It depends on how you use the car. If you frequently encounter traffic jams or short-distance commuting, the engine accumulates more carbon deposits, and the spark plugs wear out faster, possibly requiring inspection at 30,000 kilometers. If you do more highway driving, you can extend it to 60,000 kilometers. I personally replaced mine at 40,000 kilometers because delaying the replacement can lead to ignition failure, affecting acceleration and fuel consumption, or even causing the car to stall. During regular maintenance, have a technician check them, or buy a spark plug tool to measure the gap yourself to identify issues promptly. Remember, good spark plugs save fuel and are environmentally friendly, and they also help extend the engine's lifespan.
