How to properly maintain the engine in an Audi A7?

I recently bought an Audi A7 and want to make sure I am taking good care of the engine. What are some recommended maintenance steps and intervals for keeping the engine running smoothly?

Regularly check and change the engine oil according to the manufacturer's recommendations. Use high-quality oil that meets the specifications outlined in your owner's manual.

Make sure to also regularly check and replace the air filter, as a dirty air filter can reduce engine performance and fuel efficiency.

Inspect the spark plugs and ignition system every 30,000 miles and replace as needed to ensure proper engine function.
