The IPD Boxster "Competition" Plenum was designed to meet the needs of the most demanding Boxster S enthusiasts. The "Competition" Plenum is even larger and utilizes the 997 GT3 82mm throttle body allowing it to deliver even greater air flow and substantial increases in performance.
The "Competition" version is designed to work with Boxsters already equipped with "cat back" high flow performance exhaust and other performance mods.
