Description
Porsche Plenum And Y-Pipe Upgrade Kit For Porsche 991 Turbo (2014-2016) Models.
IPD Plenum and Y-Pipe Upgrade Kit for 991 Turbo
This high-performance intake upgrade kit from Innovative Pro Design is the perfect complement to Fabspeed’s exhaust enhancements, providing substantial power gains by increasing the efficiency and flow of the engine’s air intake system in your Porsche 991 Turbo. Purpose: Significantly improve engine power and torque, enhance boost response, and create a longer, more desirable power band through optimized intake airflow.
Features:
IPD Plenum:
- Designed specifically for the 991 Porsche Turbo, recognizing the engine’s similarities to the 997.2 Turbo.
-
Features a single 74mm version that utilizes the factory 74mm throttle body.
- Engineered to overcome the more restrictive intake manifolds of the 991 Turbo compared to the 997.1 Turbo.
-
The patented IPD Plenum design works exceptionally well with forced induction applications.
- Delivers impressive power and torque increases that stay above factory curves from launch to redline.
- Provides maximum power increases in the midrange, where it is most beneficial.
- Creates smooth and linear power delivery with considerably quicker boost response and a longer power band.
- Offers reliable performance for both street and motorsport applications.
IPD Y-Pipe:
- Developed through extensive R&D with unique design features and multiple prototypes
- Features larger non-round runners, an optimized merge collector area, and a proven dimpled interior surfacing.
-
Delivers greater air volume, improved laminar flow, and increased air velocity.
-
Provides an additional +35+ wheel HP and +40+ ft-lbs of Torque.
- Improves boost response and creates more linear power and torque curves.
-
The optimized non-round design with dimpled interior surface cannot be achieved with conventional round tube construction, preventing pressure drop and turbo lag.
- Direct bolt-on engine upgrade requiring no modifications.
- Comes with all necessary hardware for installation.
-
Requires an “adaptation” period achievable through hard dyno pulls or spirited driving sessions on a closed course.
- Professional installation by an experienced Porsche technician familiar with the 991 platform is highly recommended for both the Plenum and Y-Pipe.
