The perfectly balanced mid engine Cayman is Germany's canyon carving track meister. Unfortunately, the Cayman was delivered slightly under powered from the factory so as not to threaten the Carrera's throne. The Cayman IPD intake plenum delivers increased performance that puts the Cayman in the ring with the Carrera.
The IPD Cayman "Competition" Plenum was designed to meet the needs of the most demanding Cayman S 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 Caymans but produces even more horsepower gains (20+) with Caymans already equipped with after market "cat back" high flow performance exhaust and other performance mods.
IPD 3.4 - 74mm:
The 74mm Cayman S Plenum utilizes the factory 74mm throttle body. This version provides impressive power gains throughout the entire power band, especially in the midrange where it's most critical and most enjoyed.
The 74mm Cayman S Plenum application is recommended for Cayman S enthusiasts looking for considerable performance gains without pushing the performance envelope. Max horsepower is 14 and max torque is 12 which all comes in around 5600 RPM. Power gains are realized throughout the entire power band without any loses in power.
The IPD Cayman S Plenum will provides the most impressive power gains of any engine upgrade available and will truly transform your Cayman driving experience. The 74mm IPD Plenum is the best Cayman modification on the market and will further compliment other mods such as exhaust, software and beyond.
Just like the Carrera S, it's difficult to find power for the naturally aspirated 3.4L Carrera, but the IPD Plenum does it better than any other after market mod available. This simple bolt on performance upgrade replaces the factory plastic air distributor with the IPD patented aluminum "Y" style Plenum.
The IPD Plenum delivers impressive horsepower gains of 25 and torque gains of 22 by means of a superior and more efficient design. These gains are mainly felt in the mid range where it is most needed and most enjoyed but performance improvements are realized throughout the entire rev range. Impressive Performance improvements like this will truly transform your Porsche driving experience.
These added power gains in the mid range create a more liner power curve helping to minimizing the dip in power typically experienced in the factory curve resulting in considerable performance improvements.
The 996 Plenum installation is a direct bolt on R & R (remove and reinstall) procedure. Installation is relatively straight forward for mechanically inclined DIY customers although IPD strongly recommends all Plenum installations be performed by a trained and qualified Porsche technician.
