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

Volkswagen Touareg spark plugs are first replaced at 5,000 kilometers, and then every 20,000 kilometers thereafter. Below is relevant information: Volkswagen Touareg spark plugs: The original spark plugs used are NGK ZFR5EGP and Bosch Y7LER02. To replace them, open the hood, remove the engine cover, disconnect the steel wires, and use an extended socket to unscrew the old spark plugs and install the new ones. Before replacing the spark plugs, ensure the vehicle is turned off and cooled down. Spark plug replacement method: Disconnect the ignition coil wiring harness plug, remove the ignition coil fixing bolts; inspect the spark plugs (check if the terminal is damaged, if the insulator is punctured, if the electrode is worn, etc.); select the appropriate tools, assemble the tools, remove the spark plugs, and take them out one by one; cover the spark plug holes on the cylinder with a clean cloth to prevent foreign objects from entering the cylinder; align the ignition coil with the spark plug, install it in place, and use tools to screw in the bolts; clean the measuring tools, measure the spark plug gap, and evaluate the spark plugs; check the new spark plugs for any issues, place the spark plug into a dedicated socket, screw it into the spark plug hole using a digital torque wrench, tighten the spark plug, turn off the ignition switch, open the engine hood, install the three-piece set; use a digital torque wrench to tighten. Start the vehicle, clear any faults, and tidy up the workstation.
I've been driving the Touareg to work for almost three years now. Normally, I have to change the spark plugs every 60,000 kilometers or so, as recommended in the owner's manual. Last time, I delayed it until 70,000 kilometers, and the car shook badly when starting, with fuel consumption skyrocketing. After replacing them, the acceleration became smoother. Not replacing spark plugs on time can lead to poor ignition, resulting in increased fuel consumption at best and damage to engine components at worst—definitely not worth it. I usually get them replaced at the 4S shop, which doesn’t cost much, just a few hundred yuan. I recommend regular maintenance, especially for those who drive long distances frequently—it saves both hassle and money.
