How do I change my Audi A4's air filter?

I've noticed that my Audi A4's air filter is looking dirty and clogged. What steps do I need to take in order to change it and improve my car's performance?

To change your Audi A4's air filter, you will first need to locate it in the engine compartment. The air filter is typically enclosed in a rectangle-shaped box with clips or screws on the side. Unclip or unscrew the box to access the filter. Then, carefully remove the old filter and replace it with a new one. Make sure to properly align the new filter with the housing and reattach the box with the clips or screws.

Before changing your air filter, it's important to have the right tools on hand. This includes a new air filter, a screwdriver or pliers (depending on the type of clips/screws), and a rag or paper towels for cleaning any debris from the filter housing. It's also helpful to have a diagram or video tutorial for your specific Audi A4 model to ensure proper installation.
