How do I change the spark plugs in a 2002 Audi A2?

I want to change the spark plugs in my 2002 Audi A2 for better performance and fuel efficiency. Can anyone provide me with a step-by-step guide?

First, locate the spark plugs on the engine. They are usually attached to the ignition coils and can be found on the top or side of the engine. It's best to consult your vehicle's manual to find the exact location.

Next, disconnect the negative terminal of the battery to avoid any electrical shocks. Then, use a spark plug socket and ratchet to remove the old spark plugs.
