K&N 57S Air Intake Boxes

The K&N 57S Performance Airboxes are brand new TÜV compliant intake systems developed by K&N America, 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 moulded 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’s 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 say they 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 rolling road. These thoroughly engineered systems provide huge increases in power that a customer should feel when they accelerate. Typical gains on a 4 cylinder vehicle range between 4 and 7 horsepower. K&N have even tested engines that provide as much as 11 extra horsepower.

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 socket 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. K&N’s 57S Airbox is factory pre assembled and custom designed for specific vehicles to fit right into the engine compartment. The great thing is they look very similar to the factory air box, serious performance without compromising the look of your engine bay. Ideal for people that demand a factory look.

The K&N 57S Performance Airboxes are injection moulded 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.
