K&N designed a 57S performance airbox, part 57S-9501, for many Volkswagen, Skoda, Seat and Audi vehicles found mostly in Europe. The 57S-9501 was aerodynamically designed to increase airflow and reduce turbulence. K&N 57S Performance Airboxes provide up to three times the air flow compared to a K&N replacement air filter alone.
The 57S-9501 features a washable and reusable conical air filter (RU-5061). K&N 57S Air Boxes completely replace the factory air filter housing with a high flow air filter fully enclosed by an aerodynamic air box. The design reduces restriction and provides more power. The airbox has a removable lid for air filter servicing. A custom engineered velocity stack also helps to smooth and straighten airflow for added horsepower.
K&N's 57S performance airbox 57S-9501 was specifically engineered to use factory holes and mounting points. This removes any need for cutting or drilling. Installation is simple with K&N's detailed installation instructions. K&N provides an instruction sheet for select Volkswagen models and Audi, Seat, Skoda & VW models. The 57S-9501 airbox assembly was built to last for the life of your car and is protected by the famous K&N Million Mile Limited Warranty.
The 57S-9501 will fit the following vehicles:
