How do I replace the air filter on a 1990 Audi 80?

I am looking for directions on how to replace the air filter on my 1990 Audi 80. I was hoping someone could give me step-by-step instructions or provide a link to a reliable guide.

First, locate the air filter housing. This is usually under the hood in a rectangular or circular black box. Remove the lid and take out the old filter. Make sure to check and clean the housing before inserting the new filter.

When buying a replacement air filter, make sure it is designed for your specific model and year of Audi 80. This will ensure a perfect fit and maximum performance.
