The ipd Boxster s/Cayman s competition plenum was designed to meet the needs of the most demanding enthusiasts. The competition plenums 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 both bone stock Boxster s/Cayman s but produces even more horsepower gains (20+) with Boxster s/Cayman s already equipped with after market cat back high flow performance exhaust and other performance mods.

Installation is relatively easy and straight forward for mechanically inclined diy customers although ipd strongly recommends having a qualified Porsche technician perform any ipd plenum installation.
