If your vehicle is behaving badly, not willing to smoothly give the performance you expect, perhaps it is protesting a dirty Volkswagen air filter. Your vehicle needs regular maintenance to perform its best, and one of the more important maintenance procedures for good engine performance is the quick and simple job of replacing the Volkswagen air filter. If not changed often enough, your Volkswagen air filter can hamper engine performance by choking off the airflow that it needs to operate efficiently. The Volkswagen air filter gathers particles of dirt and debris from the stream of air that travels into the engine. As time goes by, the Volkswagen air filter medium will gradually become covered with this debris, allowing progressively less airflow through to the engine, likely to be the source of that bad behavior your vehicle has displayed. Such performance issues as a rough running engine, or rough idle can be caused by a clogged Volkswagen air filter, as well as poor fuel efficiency and a loss of engine power. The standard Volkswagen air filter is usually constructed with a paper filter medium to collect debris, needing periodic replacement. There are high performance versions of the Volkswagen air filter that allow a greater flow of air for better engine performance, and are made of reusable filter material, able to be washed and reused.
