K&N 57S Performance Airbox

KEY FEATURES

GUARANTEED HORSEPOWER & COMPLETE AIRBOX ASSEMBLY

Aerodynamically designed to increase airflow and reduce turbulence, providing up to three times the power gains from a K&N Replacement Air Filter alone. K&N will not sell a 57S air filter box 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. K&N have even tested engines that provide as much as 11 extra horsepower.

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.

THE WORLD'S BEST AIR FILTER™

57S Performance Airboxes are special air intakes 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 typically replaces the factory air filter box and 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 K&N 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.

K&N 57S Performance air filter boxes are injection molded from the same materials used in factory air boxes. Once installed, you will have a performance system with a factory appearance that looks as good as it performs. A 57S comes factory pre-assembled 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 K&N 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 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 filter box assembly is connected to the engine with adapters made from high strength materials such as silicone and reinforced nylon that ensures long life.

The 57S Performance Airbox features a washable and reusable oversized conical K&N High-Flow Air Filter.

EASY INSTALLATION

Sounds complicated? Thats 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. Thats because K&N specifically engineer the kits to use factory holes and mounting points so they do not require any cutting or drilling.

K&N 57S Airbox is factory pre-assembled and custom designed for specific vehicles to fit right into the engine compartment.

TÜV COMPLIANCE

Some K&N 57S Series Performance Airboxes are fully compliant with the latest TÜV emissions and sound regulations. Check the vehicle applications information below for the specific TÜV status of each vehicle and air intake.
