How do I change the spark plugs on my Audi 80?

I recently noticed my Audi 80's engine has been running rough. I suspect it may be due to the spark plugs needing to be changed. How can I safely and effectively change the spark plugs on my Audi 80?

Changing spark plugs on an Audi 80 is a fairly straightforward task. First, make sure the engine is completely cool. Then, locate the spark plugs on the engine by referring to the owner's manual. Once you have located the plugs, use a socket wrench to remove them. Next, carefully remove the old spark plugs and replace them with new ones. Finally, reattach the spark plug wires in the correct order and start your Audi 80 to test if the new spark plugs have improved engine performance.
