he 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.
Dyno-proven increases of 30-40 horsepower and 40-45 ft/lbs of torque have been achieved with this plenum. This kit includes the required 74mm throttle body upgrade and correct o-ring to seal it to the plenum. This Competition Plenum has an increased volume over the standard IPD plenum, which provides greater benefits when combined with other upgrades such as exhaust or engine software.
