Abstract: A booster container, an inlet nozzle for air entering the container and an outlet nozzle for air leaving the container, a body of liquid within the container body, the body of liquid being disposed remotely from the inlet nozzle and the outlet nozzle, a plurality of deflectors located within and attached to the container body, forming passages through which the air travels and at least one of the deflectors being partially immersed in the body of liquid. Air passes around the deflectors into the body of liquid and is influenced by a vacuum from an intake manifold, wherein the air forms bubbles in the liquid and leaves the body of liquid under vacuum and passes through the passages formed between the deflectors and leaves the booster container through the outlet nozzle connected to the intake manifold of an internal combustion engine.
