IPD Cable Throttle Plenum For Porsche 996 Carrera 2 3.4L (1999) Models.

The IPD “Y” Design Cable Plenum for early Porsche 996 C2 models is a direct replacement for the factory “T”-style air distributor. Specifically engineered for vehicles with conventional cable throttles, this plenum delivers up to 28 wheel horsepower in the midrange and an additional 12 horsepower at higher RPMs, providing a noticeable boost in performance across the rev range.

As a bolt-on upgrade, the IPD Plenum dramatically enhances throttle response and overall driving enjoyment, making it one of the most effective modifications for early underpowered 996 Carreras. Installation is straightforward for mechanically inclined enthusiasts, though IPD strongly recommends having a qualified Porsche technician perform the upgrade to ensure optimal results. To determine if your 996 uses a cable or E-gas throttle, check the throttle body for either a black electronic module (E-Gas) or a conventional spring/cable mechanism.
