How do I change the spark plugs in an Audi A5?

I am having trouble accessing the spark plugs in my Audi A5. Can someone provide step by step instructions or tips for changing them?

First, locate the spark plugs on the engine. They are typically located near the top of the engine and are connected to thick wires. Next, use a spark plug socket and extension to remove the old spark plug. Be sure to check the gap on the new spark plug before installing it. Finally, carefully screw the new spark plug into place and reattach the wire. Repeat for all spark plugs.
