Engine Air Filter Replacement

Model: Audi A4 B6 - Years 2000-2004
Part: Air filter

Once you open the hood, locate the engine air filter box (air box) and remove the screws securing the cover to lift it and extract the old filter (to facilitate this operation, it is suggested to disconnect the intake hose where the mass air flow sensor is attached); after removing the old filter, clean the filter box of any dirt residue, ensuring no debris enters the intake duct: using a vacuum cleaner is an excellent solution. Then, insert the new filter, ensuring the gaskets fit perfectly, and reposition the cover.
