IPD Plenum 74mm For Porsche 996 Carrera 3.4L (2000-2004) Models.

The IPD Plenum for the Porsche 996 Carrera 3.4L is a direct bolt-on performance upgrade that replaces the factory plastic air distributor with IPD’s patented aluminum “Y” design. Engineered for maximum airflow efficiency, this plenum delivers an additional 25 wheel horsepower and 22 lb-ft of torque, with the most noticeable gains in the midrange while improving performance across the entire rev range.

By smoothing the power curve and reducing the dips found in the factory system, the IPD Plenum enhances throttle response and provides a more engaging driving experience. Installation is a straightforward remove-and-reinstall procedure suitable for mechanically inclined enthusiasts, though IPD strongly recommends having a trained Porsche technician perform the installation for optimal results and reliability.
