How often should I change the spark plugs on my Audi A4?

I have a 2017 Audi A4 and I am wondering how often I should replace the spark plugs. I currently have 50,000 miles on my car and I am not sure when the last time they were changed. I'm a bit nervous about attempting to change them myself, so I would appreciate any advice or tips on when to replace them and if it's something I can do on my own.

It is typically recommended to replace spark plugs every 30,000 miles or so, but it ultimately depends on your specific car model and driving habits. Since you have 50,000 miles on your Audi A4, it would probably be a good idea to replace them soon. As for changing them yourself, it can be a bit tricky, so I would recommend consulting your owner's manual or watching some online tutorials before attempting it.
