Vivid Racing's Stage 3 kit for the Porsche 997 Carrera adds 1 key component to the system, the IPD Intake Plenum.  The IPD intake plenum is designed to improve the air flow after the throttle body as it goes into each cylinder head.  The IPD cast piece is in the shape of a "Y" which features a coated inside surface to achieve the most efficient air flow design.  This plenum has been tested to improve torque, throttle response, and mid range RPM gains.  Our Stage 3 kit includes all of the Stage 1 and 2 parts as well.  Expect to gain 55 Horsepower to the crank with our Stage 3 kit.
