How can I replace the spark plugs in an Audi 80?

I recently noticed that my Audi 80 is not running as smoothly as it used to. I suspect it's time to replace the spark plugs, but I'm not sure how to do it. Can anyone provide some guidance?

To replace the spark plugs in your Audi 80, you will need a spark plug socket, a ratchet, and a spark plug gap tool. Start by disconnecting the negative battery cable, then remove the spark plug wires and use the socket and ratchet to remove the old spark plugs. Check the gap on your new spark plugs with the gap tool and adjust if necessary before installing them. Finally, reconnect the spark plug wires and the battery cable.

Replacing spark plugs is a simple task, but it's important to use the correct type of spark plugs for your specific Audi 80 model. Consult your owner's manual or a trusted mechanic to determine the right spark plug for your car. I also recommend changing all the spark plugs at once, even if only one appears to be faulty, to ensure smooth and consistent performance.
