How do I replace the spark plugs on a Audi 80?

I just bought a used Audi 80 and I noticed it's been running rough. I want to replace the spark plugs, but I'm not sure how to do it. Can someone guide me through the process?

The first step is to locate the spark plugs. They are usually located in the engine compartment and can be identified by the thick wires attached to them. Use a spark plug socket to remove the old one and replace it with a new one. Make sure to torque it to the correct specifications.

Before replacing the spark plugs, make sure your engine is completely cooled off. Removing the spark plugs while the engine is still warm can result in damage to the threads. It's also a good idea to replace the spark plug wires while you're at it.

It's always a good idea to consult your Audi 80's manual for specific instructions and torque specifications. In general, you should replace your spark plugs every 30,000 miles for optimal performance.
