K&N Filters 57S Performance Airbox

The K&N 57S Performance Airbox replaces the original airbox with a fully enclosed, purpose designed, injection moulded airbox and K&N high flow filter. The enclosed airbox means cool air is retained and fed to the engine without external heat sources affecting inlet temperatures. The oversized conical filter and the custom engineered Velocity Stack (Velum) have been designed to increase, smooth, and straighten airflow - allowing maximum cool air for increased power. By reducing both the air filter and air box restriction, these systems provide up to three times the power gains available with a K&N replacement air filter.The airbox features a removable lid for easy servicing, and the filter is completely washable and reusable, meaning you never have to buy another filter again.Guaranteed horsepower - aerodynamically designed to increase airflow and reduce turbulence, providing up to three times the power gains from a K&N replacement air filterSpecifically designed to use original airbox mounting points so no additional hardware, cutting or drilling is requiredK&N Million Mile Limited WarrantyFully complies with the latest TUV emissions and sound regulationsK&N's 57S Performance Airbox is a TUV compliant intake system.
