How often should the spark plugs be replaced in an Audi A3?

I have recently purchased an Audi A3 and I am wondering about the maintenance schedule for the spark plugs. How frequently should I replace them and what factors might affect their lifespan?

It is recommended to replace the spark plugs every 50,000 miles or every 5 years, whichever comes first. However, factors such as driving habits and fuel quality can also impact the lifespan of the spark plugs.

If you notice a decrease in engine performance or difficulty starting the car, it may be time to have your spark plugs replaced. It's always better to err on the side of caution and replace them sooner rather than later.
