The 997 marked Porsche's return to the round headlights and curvaceous fenders reminiscent of the 993 and earlier era Carreras. Although the 997's picturesque styling is another milestone in Porsche design history there is still room for improvement in the engine performance department.

The IPD "Y" design plenum replaces the factory "T" style air distributor and provides substantial power and torque gains by means of a more efficient design. Horsepower gains range from 24 to 28  depending on engine displacement and engine condition. These max power gains are experienced in the mid range where is it most useable and enjoyed.

The IPD Plenum not only delivers impressive power and torque increases but also creates a more linear power and torque band. Tiptronic customers even claim considerable improvements with more positive shifting after installing the IPD Plenums.

997.1 Carrera Comp Plenum is available with 2 different silicone hose options. Part # 97182 includes the custom IPD silicone hose designed to fit the 82mm GT3 throttle body and factory Porsche air box. Part # 97182-RH includes a straight silicone reducer hose coupler that fits the 82mm GT3 throttle body and most popular after-market air intake systems that replace the factory air box.
