System for improving the efficiency of an internal combustion engine of a vehicle

A method for improving the efficiency of an internal combustion engine of a vehicle, the method comprising:

• positioning a first non-rotating device within an air intake manifold upstream from a throttle chamber of the engine;
• positioning a second non-rotating device within an exhaust manifold of the vehicle;
• engaging the first and second devices to the inner surface of the air intake manifold and exhaust manifold, respectively;
• and
• generating a spiral airflow using the first and second devices such that a differential air pressure is created to accelerate the rate of airflow through the vehicle.

A kit for improving the efficiency of an internal combustion engine of a vehicle, the kit comprising:

• a first non-rotating device to be positioned within an air intake manifold upstream from a throttle chamber of the engine;
• and
• a second non-rotating device to be positioned within an exhaust manifold of the vehicle;
• wherein the first and second devices include:
• a tubular housing having an entrance end portion and an exit end portion, the housing being of a size to direct the flow of air through the air intake manifold or the exhaust manifold from the entrance end portion to the exit end portion;
• a plurality of longitudinal fins arranged within the housing extending from the entrance end portion towards the exit end portion, the fins having a curved profile to generate a spiral airflow such that a differential air pressure is created to accelerate the rate of airflow through the vehicle.
