Dinan D760-0013 - High Flow Cold Air Intake System; 18 Max Horsepower Gain At 6500 RPM; 15 lbs.-ft. Max Torque Gain;

Dinan high flow intake system for the 550i dramatically increases intake air-flow volume and velocity as well as ensuring the lowest possible intake air temperatures for maximum power gains, as well as improved throttle response. The system takes full advantage of the ram-air effect by adding a second air inlet in conjunction with the stock configuration, force-feeding more cool, oxygen-rich air to the enhanced air box. The system includes a complete replacement air box and lid, designed to increase overall volume and accommodate the additional air inlet. A special high flow filter element is included, reducing the restriction presented by the stock filter. The airbox and lid are molded from a composite material that has been chosen specifically for its ability to resist power robbing under-hood heat and the design provides for a completely sealed air box, maximizing pr
