Abstract
In accordance with exemplary embodiments, a variable air intake system and method is provided for a vehicle. The system comprises an engine a controller coupled to the engine. The controller also couples to and controls an air intake system including a first air inlet port and a second air inlet port having a valve operable to move between a closed position and an open position responsive to the controller to provide air to the engine via a filter. A sensor is disposed between the filter and the engine to communicate with the controller for controlling the valve. The method comprises determining engine speed and air flow for an engine of a vehicle and comparing via the engine speed and air flow to a respective high threshold and low threshold. A valve within a second (controlled) air inlet port is opened when the engine speed and air flow each exceed the respective high threshold and closed when the engine speed and air flow each are below the respective low threshold.
