How do I change the spark plugs in an Audi A6?

I am having trouble figuring out how to change the spark plugs in my Audi A6. Can someone provide me with step-by-step instructions?

Step 1: Open the hood and locate the spark plugs. They are typically located on top of the engine and have black rubber boots attached to them.

Step 2: Use a spark plug socket and ratchet to remove the old spark plugs. Turn them counterclockwise to loosen and remove them.

Step 3: Insert the new spark plugs into the socket and tighten them by turning them clockwise. Make sure they are snug but not too tight.
