IPD Competition Plenum 74mm For Porsche Boxster 986 S 3.2L (2000-2004) Models.

The IPD Plenum for the Porsche 986 Boxster is engineered to enhance the performance of the mid-engine roadster, providing noticeable gains in both horsepower and torque across the entire power band. Featuring IPD’s patented “Y” design and designed to work with the larger 74mm throttle body, this plenum improves airflow and intake air velocity, unlocking the Boxster’s full performance potential.

For the 986 Boxster S 3.2L, the IPD Plenum delivers over 15 wheel horsepower and 15 lb-ft of torque, with the most significant improvements felt in the midrange. The upgrade is ideal for both stock and lightly modified vehicles, requires no ECU changes, and comes complete with a custom silicone hose and all necessary hardware for installation. While the installation is relatively straightforward, IPD strongly recommends that it be performed by a qualified Porsche technician to ensure optimal performance and reliability.
