The new 991.2 turbocharged Carrera Plenums are now available for new Carrera drivers looking to raise the performance bar of their 3.0L turbo engines. The Carrera Plenum is very similar to the Turbo Plenum with only minor modifications to the hardware package. No official testing has been conducted as of yet but based on past experience and customer feedback we expect power gains to be in the mid 30+ range and torque over 40. Stay tuned for dyno testing coming as soon as we get our hands on a test car.

987 Competition Cayman 2.7L & 3.4L Plenum: HP Gains 20+ / Torque Gains 18 Requires upgrading factory 74mm Throttle Body with 997 GT3 82mm Throttle Body
Recommended to be installed on modified Caymans with Hi-Flow Cat back exhaust
Download the detailed installation instructions.
The perfectly balanced mid engine Cayman/Boxster is Germany's canyon carving track meister. Unfortunately, the Cayman/Boxster was delivered slightly under powered from the factory so as not to threaten the Carrera's thrown. The Cayman IPD intake plenum delivers increased performance that puts the Cayman/Boxster in the ring with the Carrera.
The IPD Plenum out performs every other intake system on the market. Don't be fooled by other competitors claiming to offer Plenums. All factory Porsche air distributors are of the "T" variety and therefore suffer from less than ideal air flow and intake air speed.
The genius and power behind the IPD plenums comes from the patented "Y" style design and optimized diversion areas to deliver real and impressive power that will transform your Cayman's/Boxster's performance and heighten your Porsche driving experience.
The Cayman/Boxster IPD Intake Plenums are available in 3 versions, each one specifically designed to meet the performance requirements of varying Cayman/Boxster enthusiasts. IPD offers the ultimate Cayman/Boxster performance upgrades, all the way from mild to wild.
The IPD Cayman/Boxster "Competition" Plenum was designed to meet the needs of the most demanding Cayman/Boxster 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/Boxsters but produces even more horsepower gains (20+) with Caymans/Boxsters already equipped with after market "cat back" high flow performance exhaust and other performance mods.

In fuel injected engines, the throttle body is the part of the air intake system that controls the amount of air flowing into the engine, in response to driver accelerator pedal input in the main. The throttle body is usually located between the air filter box and the intake manifold, and it is usually attached to, or near, the mass airflow sensor.
The largest piece inside the throttle body is the throttle plate, which is a butterfly valve that regulates the airflow. Have a larger diameter throttle body produces more air flow with equals more power. The upgrades should be used in conjunction with the competition plenums.
This is a 74mm Throttle body.
