What type of spark plugs should I use in my Audi 80?

I recently purchased a used Audi 80 and I'm not sure what type of spark plugs to use. Should I go with the original equipment manufacturer (OEM) plugs or is there a better option? What are the potential drawbacks of using aftermarket plugs?

For your Audi 80, I would highly recommend sticking with OEM spark plugs. They are specifically designed for your car and will ensure optimal performance and longevity. Aftermarket plugs may claim to have better performance, but they could also cause issues such as misfires and reduced fuel efficiency.
