Abstract
A throttle body for use in the air intake system of a motor vehicle comprising a throttle body defining a throttle bore. The throttle plate is rotatably mounted within the throttle bore, having an outside diameter smaller than an inside diameter of the throttle bore. A plurality of fins, located on the throttle plate, extend from the throttle plate in a direction generally perpendicular to a plane defined by said throttle plate. The fins are optimized in number, thickness, spacing, length, shape, and angle to reduce air-rush noise without impacting engine performance.
