How to change the spark plugs on an Audi A8?

I have noticed my Audi A8 is running a bit rough and someone mentioned it could be because of the spark plugs. How do I change them myself?

Firstly, check your owner's manual for the correct type of spark plugs for your Audi A8. Once you have the right ones, gather your tools including a spark plug socket and ratchet, and get to work.

Locate the spark plugs, they are usually located in a row on either side of the engine. If you are unsure, refer to your owner's manual or a trusted mechanic for guidance.
