400-633 PowerAid Throttle Body Spacer for the 2009, 2010 Ford F150 4.6L 3v V8. You can install this unit in minutes with basic hand tools.The PowerAid® was developed to enhance your vehicle’s off idle to mid range performance and efficiency. The unique “Helix Bore” design of the PowerAid creates a spinning action of the incoming air. As air passes through your throttle body, this helical effect causes the air molecules to organize and maintain high velocity. The organization and high velocity of the air is extremely beneficial because it helps to provide a superior atomized mixture of fuel and air all the way into the combustion chamber. The benefits you will see are tremendous torque gains between 800 to 2500 RPM, and potential increases in your fuel economy, depending on driving conditions.
