Our air filter sock is a fine filter cover for the intake, which not only protects the engine, but also your air filter. It protects against coarse particles and fine dirt , significantly extending the maintenance intervals and life of the air filter, turbo and engine! It is therefore the ideal complement for our 2.0L TSI EA888 Open Air Intake ! Air filter sock: Longer life of your engine We developed the sock especially for the air filter of our EA888 intake . It acts like a nylon filter that is simply pulled over the air filter. So it already protects the filter efficiently, both from coarse and the smallest contaminants. As a result, particles can no longer enter the intake, which also reduces the load on the engine and turbo. At the same time, the protective filter sock does not restrict the intake. So all the benefits of our 2.0L TSI EA888 open air intake are unaffected . Ultimate match for our intake We have developed the sock especially for our Open Air Intake. To really optimize your air intake, we recommend to mount it in combination with our sock. This way you benefit from all advantages and from perfectly matching parts . Advantages of the fine filter cover in conjunction with our EA888 intake : Longer service life of the air filter, engine and turbos Protection against coarse and fine contamination Significantly extended maintenance intervals Up to 25 PS (18 kW) more power Powerful sound Cool intake air with high boost TÜV included Easy installation: Sock over the filter and you're ready to go! ) - Made with ❤ - Manufacturer Information about the manufacturer BAR-TEK BAR-TEK Motorsport GmbH Im Rauschen Auel 3, 51491 Overath-Brombach, Germany info@bar-tek.com
