K&N 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 airbox and air filter with upgraded high quality components. A 57S uses a fully enclosed airbox assembly with a removable lid for easy access to the filter when cleaning is required. The 57S airbox 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 airbox restriction, these systems provide up to three times the power gains available with a K&N replacement air filter that go into the factory airbox. The weakest link in the airflow "chain" robs a vehicle of its natural horsepower. Often that weak point is the factory airbox itself, a problem K&N has solved with the 57S.
GUARANTEED HORSEPOWER - K&N will not market a 57S system that does not provide a measured increase in horsepower and torque. Each system is proven to increase vehicle power at the wheels on a dynamometer. These thoroughly engineered systems provide huge increases in power that a customer will 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.
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. The 57S Airbox is factory pre-assembled and tailor made for specific vehicles to fit right into the engine compartment.
