Upgrade your factory air intake to a K&Ns 57S Performance Airboxes. This will increase horsepower and acceleration by dramatically reducing air flow restriction caused by the original factory design. They come with K&Ns Million-Mile Limited Warranty. 57S series airboxes replace the factory air filter housing with a fully enclosed injection modified air box containing a reusable K&N air filter. Installation is easy as they are specifically engineered to use factory holes and mounting points. No additional hardware, cutting or drilling is required.
This intake system adds power that you can feel on your TSI engine, and increases throttle response throughout the entire rpm range. The air filter is the standard K&N washable cone filter, so there is no need to ever purchase a new filter.

More Power for Volkswagen, Skoda, Seat and Audi Models with K&N 57S Performance AirBox
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 power 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.
K&N 57S Airbox: K&N 57S Series Performance Airbox Assemblies
THE WORLD'S BEST AIR FILTERé
The 57S Performance Airbox features a washable and reusable oversized conical K&N High-Flow Air Filter.
COMPLETE AIRBOX ASSEMBLY
Replaces the factory air filter housing with a fully enclosed injection modified air box to reduce sound and cool air. The airbox comes with a removable lid for servicing and a custom engineered Velocity Stack (Velum) designed to smooth and straighten airflow for added power.
Aerodynamically designed to increase airflow and reduce turbulence, providing up to three times the power gains from a K&N Replacement Air Filter alone.
Specifically engineered to use factory holes and mounting points so no additional hardware, cutting or drilling is required.
K&N MILLION MILE LIMITED WARRANTY
The entire airbox assembly is built to last for the life of your car.

57S Performance Airboxes are special air intake systems developed by K&N, the inventor of the Million-Mile High-flow air filter. These systems increase horsepower and acceleration by dramatically reducing air flow restriction caused by the original factory design. A K&N 57S completely replaces the factory air box and air filter with upgraded high quality components. A 57S uses a fully enclosed air box assembly with a removable lid for easy access to the filter when cleaning is required. The 57S air box is injection molded for extra strength, consistency and durability. The 57S assembly is large enough to house an oversized conical K&N High Flow air filter and the entire product is backed by our Million Mile Limited Warranty. By reducing both air filter and air box restriction, these systems provide up to three times the power gains available with a K&N replacement air filter that go into the factory air box. The weakest link in the airflow "chain" robs a vehicle of its natural horsepower. Often that weak point is the factory air box itself, a problem K&N has solved with the 57S.
We will not sell a 57S system that does not provide a measured increase in horsepower and torque (acceleration). Each system is proven to increase vehicle power at the wheels on a dynamometer (think treadmill for cars). These thoroughly engineered systems provide huge increases in power that a customer should feel when they accelerate. Typical gains on an 4 cylinder vehicle range between 4 and 7 horsepower. We have even tested engines that provide as much as 11 extra horsepower.
INCREASE UP TO 11 HORSEPOWER!!

CONICAL K&N HIGH-FLOW AIR FILTER
K&N's 57S-9500 high-flow air filter assembly uses an oversized conical K&N high-flow air filter
Sounds complicated? That's the great part, these systems are easy to install. A typical installation can be done with a screwdriver, pliers and a ratchet set in 30 minutes. That's because we specifically engineer the kits to use factory holes and mounting points so they do not require any cutting or drilling. Our 57S Airbox is factory pre assembled and custom designed for specific vehicles to fit right into the engine compartment.
THE WORLD'S FIRST MILLION-MILE WARRANTY
K&N invented the world's first air filter guaranteed for one million miles. That same warranty stands behind our 57S Performance Airbox. Engineered with care and passion, these systems are built to last for the life of your car. We stand behind them completely.
Our 57S Performance Airboxes are injection molded from the same materials use in OE air boxes. Once installed, you will have a performance system with an "OE" look that looks as good as it performs. A 57S comes factory pre assembles and has a removable lid to make servicing the washable air filter simple. Inside the 57S is the largest conical shaped High-Flow air filter we could fit into the system while still using factory holes and mounting points. This extra filter size provides even more airflow at lower restriction than a standard K&N O/E replacement filter that is limited to the size of the factory air box. The oversize air filter also captures and holds more dirt increasing the service life before a cleaning is required to 100,000 miles under normal on-highway driving conditions. The air box assembly is connected to the engine with adapters made from high strength materials such as silicon and reinforced nylon that ensures long life.
About Manufacturer: K&N
Leader of High Flow Performance Air Filter
K&N users would probably be surprised by the amount of air filtration testing and scientific research that goes on in K&N facilities as well as in independent laboratories. As the leader and originator of the high flow performance air filter we are always looking for new ways to provide excellent protection and maximum power for your car, truck, motorcycle, and just about anything else with an engine. In 2005 more than 1600 vehicles were tested by K&N's R&D group on dynamometers in the US, United Kingdom, and the Netherlands. In addition to these power and torque tests, we also performed more than 110 filtration tests and more than 1,200 air flow tests with our in-house state-of-the-art test equipment.
