Audi has come a long way as a leading manufacturer of exquisite cars---attractive, sophisticated and technically proficient. The European car maker strives to run toe-to-toe with its rivals through the company's innovations and standards, which is consistent with the brand's claim of "progress through technology.” Just like any other vehicles, Audi's roster of cars such as A3, A4, and TT, rely heavily on well-integrated performance parts. It is for this reason why owners who are looking for Audi Aftermarket Parts should take into consideration the quality and specific benefit/role of each part.

An important Audi aftermarket part is the Audi Air Filter. A typical Audi Air Filter is a disposable, pleated-paper element with a sealing gasket made of synthetic material. Audi air filters are available in two main types: the panel style as used in most fuel-injected cars and the radial style, found in carbureted vehicles. An Audi Air Filter that is in tiptop shape traps dirt particles, which can cause damage to engine cylinders, walls, pistons and piston rings. Audi air filters also keep contaminants off the airflow sensor, which is attached in some fuel-injected cars. The filter sometimes cleans the air that enters the crankcase ventilation. Hence, the Audi Air Filter also serves as a silencer for the car’s intake system. A typical automobile engine uses more than 10,000 gallons of air for every gallon of fuel burned. Because of this, air filter's role is very important.

Although there may be a prescribed in-between inspection period for the air filter, a checkup coinciding with oil change could be a good precautionary measure. Yet, dirty and dusty driving conditions require more frequent filter replacements, so keep this in mind. Driving with a dirty filter restricts the air entering the engine, eventually affecting fuel economy and performance. Most Audi air filters can be easily replaced by removing snap clips, a clamp or several screws. Just like any other Audi Aftermarket Parts, the replacement Audi Air Filter cut out exactly for an owner's vehicle. An erroneously-fitted filter may allow unrestricted air into the engine, causing engine damage.
