How do I properly change the spark plugs of an Audi 80?

I have noticed decreased performance in my Audi 80 and I suspect it may be time to change the spark plugs. However, I have never done this before and I am not sure where to start. Can someone provide a step-by-step guide on how to change the spark plugs in an Audi 80?

First, gather your tools including a socket wrench, spark plug socket, and gap tool. Then, remove the spark plug wires from the old plugs and use the socket wrench to remove the old plugs. Make sure to properly gap the new spark plugs before inserting them and reattach the spark plug wires in the correct order.

I recommend watching a tutorial video before attempting to change the spark plugs. It is a simple process, but seeing it done can be helpful. Also, be sure to purchase the correct spark plugs for your specific Audi 80 model.

You should change your spark plugs every 30,000 miles or every 3 years, whichever comes first. Neglecting to change them can lead to decreased fuel efficiency and engine performance.
