The air filter removes soot, carbon, abrasives and other contaminants from the air before the air mixes with fuel in the engine induction system. Like oil filters, air filters can be easily overlooked. They often don't get replaced until they are absolutely clogged with dirt and soot and this simply isn’t good for your vehicle. Pick up this replacement air filter and restore air flow to your engine, maximizing power and fuel efficiency. Genuine Audi replacement filter, part number: 4G0133843L
