Is it necessary to change the spark plugs in an Audi A6?

I've heard that it's recommended to change spark plugs in a car after a certain amount of time, but is it really necessary for an Audi A6? This car is supposed to have a high-quality engine, so is it actually worth the time and money to change the spark plugs?

Yes, it is definitely necessary to change the spark plugs in your Audi A6. Even though it has a high-quality engine, spark plugs still wear out over time and can affect your car's performance if they become too worn.
