57i Performance Kit

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

A look under the bonnet of modern cars with fuel injection is enough to realize that the air supply is hampered by unnecessary angles and distances. However, just needed air induction and a filter of the air to pass through without much resistance. The success of the 57i kit is in development. Using special equipment, the air flow is measured and determined from this data, the correct filter size. Dynamometer tests ermittel then not only yield the best performance, but also value torque curve, the response and the economy is down.
