IPD Plenum (74mm Throttle Body) - 987.1 Boxster / Cayman 2.7L, 3.4L S

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 throne. 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 74mm Cayman/Boxster 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/Boxster S Plenum application is recommended for Cayman/Boxster 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/Boxster S Plenum will provides the most impressive power gains of any engine upgrade available and will truly transform your Cayman/Boxster driving experience. The 74mm IPD Plenum is the best Cayman/Boxster modification on the market and will further compliment other mods such as exhaust, software and beyond.

This Plenum fits: 

Porsche 987.1 Boxster / Cayman S 3.4L

Porsche 987.1 Boxster / Cayman 2.7L

(Some early (<2006) models have a 68mm throttle body, and will require the purchase of a 74mm throttle body)
