OEM air filter for 2003-2004 Audi RS6 C5. This model requires two (2) of these filters. Please order two (2) for the complete air filter replacement.
If an air filter is doing it's job, it will get dirty. As a filter gets dirty, the amount of air that can flow through it is reduced. Without the proper amount of air, the engine will not be able to produce the power it should; nor it will be as fuel efficient as it should be. Make sure your car is breathing only the freshest air with this high-quality OEM air filter.
