K&N's 57S Performance Airboxes increase horsepower and acceleration by dramatically reducing air flow restriction caused by the original factory design. They are TÜV compliant and come with K&N's 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.

K&N's 57S Performance Airboxes are brand new TÜV compliant 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. This innovative design delivers extra power and complies with the latest TÜV emissions and sound suppression regulations. 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 their 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.

INCREASE OF UP TO 11 HORSEPOWER!

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.

EASY INSTALLATION

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 K&N 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.
