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.
This competition plenum is the ideal upgrade for a 997 that's already seen light modification. This kit includes the required 82mm throttle body upgrade from the 997 GT3 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.
Dyno-proven increases of 15 peak wheel horsepower and 12 peak ft/lbs of torque, along with 23 wheel horsepower and 21 ft/lbs of torque at 6000 RPM (when paired with supporting modifications) have been achieved with this plenum. Will require a tune for optimal performance and to prevent a check engine light.
