Power Now Air Intake System: The Scary Fast POWERNOW provides bigger horsepower improvements, greater power at 1/4 and 1/2 throttle for 2-strokes, 4-strokes, mini bikes and ATVs. Mounted into the backside/airboot side of the carburetor, the Power Now , slices the single air venturi going into the carburetor into 2 smaller, faster, venturis via the PowerNow s Power Plate . Our trademarked revolutionary Power Plate assists the vacuum of the fast moving air by drawing the fastest moving air molecules through a precisely positioned hole in the plate, drastically increasing the speed of the top and bottom venturis entering the cylinder. With this modification, the result is volumetric engine efficiency through uncompromised airflow velocity.
