Product Details

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 thrown. The Cayman IPD intake plenum delivers increased performance that puts the Cayman 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 performance and heighten your Porsche driving experience.The Cayman IPD Intake Plenums are available in 3 versions, each one specifically designed to meet the performance requirements of varying Cayman enthusiasts. This IPD Intake Plenum offers the ultimate Cayman performance upgrades, all the way from mild to wild.


  • Internal dimpling
  • Smooth and linear power

About Innovative Pro Design (IPD)

Innovative Pro Design (IPD) was founded in 2004 by Mike "Turbo" Kirakosyan. The IPD Plenums were conceived, developed, tested, proven and manufactured in the heart of the Porsche Tuning capital, Southern California. The IPD plenums evolved from the age old hot rod philosophy of "never leave good enough alone". The genius behind the IPD Intake Plenums is not only the patented "Y" design but also the geometry of diversion areas, optimization of bore sizes and internal surface area manipulation.

Virtually all performance upgrades stem from man's innate and unstoppable quest for speed and power, and the IPD Plenums are no exception. Turbo Mike's "Need for Speed" is embedded in his DNA. His relentless pursuit of performance extends well beyond the Plenums. Mike is an accomplished fabricator, engine builder, tuner and all around Porsche expert.
