The revolutionary and patented design of the IPD Porsche Plenums improve intake air flow by replacing the factory plastic "T" style design with a more efficient, cast aluminum "Y" design. The IPD Plenums distribute the air flow more effectively by using a true merge collector and reducing pressure drop at the throttle body inlet. This innovative Y diversion area of the IPD Plenums split and channel intake air flow reducing air flow turbulence and increasing air flow velocity. This superior and proven design ultimately results in considerable power gains throughout the horsepower and torque curves.
Designed for use in conjunction with a 74mm throttle body.
