Dinan's high flow intake system for the 650 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 inlet configuration, force feeding cool, oxygen rich air to the modified air box. The system includes a replacement air box lid, designed to increase overall volume and accommodate a special high flow filter element.
The high flow intake system alone results in a substantial 18 horsepower gain. The system also provides a subtly more aggressive intake note that is sure to be music to the driving enthusiasts' ears.
