The Audi S4 was designed to replace the outgoing C3. Audi S4 has made and marketed lots of quality vehicles and parts. Serious issues may occur if Audi S4's air filter is not in good condition, including allergy, reduction in airflow, reduced performance, misfire, greater oil consumption as well as completely messing up the vehicle.
Although Audi S4 has lots of auto parts with nice performance, the air filter still needs to be repaired after a long time of usage. If Audi S4 air filter parts are in the housing make sure to disconnect all hoses going to the housing so they do not get torn during removal. When servicing Audi S4's air filter, you should pry open the housing (if equipped) and remove the old unit first. Next, reposition the new air filter making sure the top is facing the top and the bottom is facing the engine. Then, reconnect the pins on Audi S4's air filter box or reattach the wingnut (carbureted engines). Finally, reconnect all hoses and connections going to housing.
