Description
Dinan's high flow intake system for the 550i dramatically increases intake air-flow volume and velocity, ensures the lowest possible intake air temperatures for maximum power gains, and improves 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 chosen specifically for its ability to resist power robbing under-hood heat.
The design provides a sealed air box, maximizing pressurization for optimum performance. Air from the secondary inlet passes through custom-molded ducting, including a visible section manufactured from carbon fiber, also designed to reject underhood heat and provide maximum flow.
The high flow intake system alone produces a substantial 18 horsepower gain. The intake note takes on a subtly more aggressive tone at a wide-open throttle that will be music to the driving enthusiasts' ears.
