Almost nothing else can deliver as much performance for so little money as a K&N 57i Performance Kit. This kit replaces the original filter box and dramatically reduces the air resistance in the intake system.

A look under the hood of modern vehicles with injection systems is enough to see that the air supply is being blocked by unnecessary angles and paths. Air just needs suction paths and a filter that lets this air through without much resistance. The success of the 57i kits lies in development. The air flow is measured with special devices and the correct filter size is determined on the basis of this data. Test bench tests then not only determine the best power output, but emphasis is also placed on torque curve, responsiveness and economy.
