Porsche 987.1

IPD Competition Plenum for Porsche 987.1 Boxster/Cayman The IPD Competition Plenum for your 987.1 Boxster/Cayman (2005-2008) delivers increased performance that puts the Boxster and Cayman in the ring with the Porsche 911 Carrera! The perfectly balanced mid-engine Boxster and Cayman are Germany's canyon carving track meisters. Unfortunately, they were designed to be slightly under-powered from the factory so as not to threaten the 911's throne. The IPD Competition Plenum delivers increased performance that puts the Cayman in the ring with the Carrera. The IPD Competition Plenum outperforms every other intake system on the market. IPD's patented "Y" design and optimized diversion areas deliver real, usable power that transforms the Boxster or Cayman's performance on both the street and race track. The IPD Boxster/Cayman Competition Plenum was designed to meet the needs of the most demanding Porsche enthusiasts. Its higher flow characteristics utilize the GT3's 82mm Bosch throttle body (available as an add-on above), allowing it to deliver greater air flow, better fuel/air mixing and substantial increases in performance. The IPD Competition Plenum unlocks performance even with your stock exhaust. It is optimized to work in conjunction with a cat-back high flow performance exhaust and high-flow intake filter, so you can continue to unlock performance in the future. (These are not required, but are preferred.) Bosch 82mm throttle body is required, which can be added to your order above for only $225.
