Description
The IPD Performance Intake Plenum for the Porsche 958 Cayenne Turbo 4.8L is a high-performance bolt-on upgrade designed to significantly enhance airflow efficiency, boost response, and overall engine performance for Porsche’s flagship SUV platform from 2011–2018.
The Cayenne Turbo is widely recognized as one of the most powerful and capable performance SUVs in Porsche’s lineup, combining practicality with true sports-car-level driving dynamics. The IPD Plenum further elevates this performance by improving intake airflow and optimizing the way the engine delivers power under boost.
This upgraded plenum features an enlarged inlet design and optimized internal diversion area that increases intake air velocity while reducing turbulence. The result is improved engine breathing, faster boost response, and a more linear and consistent power delivery across both power curves.
The IPD Cayenne Turbo Plenum is engineered to work with the factory OE 76mm throttle body and utilizes all original factory hardware for a straightforward installation.
One of the key benefits of the IPD design is durability. Factory plastic intake components are known to be susceptible to cracking under higher boost levels, whereas the IPD plenum is engineered for increased strength and long-term reliability under elevated performance conditions.
