How do I change the air filters on an Audi A7?

I've noticed that my Audi A7's air filters are dirty and need to be changed. How can I do this myself instead of taking it to a mechanic?

Changing the air filters on an Audi A7 is actually a pretty simple task. First, locate the air filter housing under the hood of your car. It should be a large, rectangular box with clips or screws holding it closed. Once you have opened the housing, take out the old air filter and replace it with a new one. Make sure the new filter is properly aligned and then close the housing. You may also want to use a vacuum cleaner to remove any debris from the housing before placing the new filter.
