A nozzle air injection (NAI) system and algorithm for fuel-injected engine for increasing the flow of air into the engine. In one embodiment the NAI system takes the form of a kit comprising a controller, engine speed and throttle position sensors, a power regulator, an air compressor adapted to be rotatably driven by an electric motor to drive additional air into the engine. The controller includes a processor and sufficient memory to perform the logic steps necessary to selectively operate the compressor. In one embodiment, the controller checks the status of engine speed and throttle deflection and if the engine speed is equal or less than a first threshold value, and if the throttle deflection is greater than or equal to a second threshold value the controller instructs the regulator to send electrical power to the motor to drive the compressor to provide additional air to the engine.
