We are delighted to unveil our bespoke Plenum specifically designed for the Porsche 911 996 Turbos This highflow Plenum is designed to enhance the performance of your 996 Turbo remarkably
Key Features
- Engineered to work with the throttle body from 9971 Turbo Part number 99760511500 to address the air flow restrictions of the OEM 996 throttle body
- Includes two silicone hoses for compatibility with both the do88 performance Ypipe TR360 and the OEM Ypipe
- Crafted from highquality cast pipe with precision CNCmachined connections
- Smooth interior surface for optimal air flow
- Equipped with all required accessories for hasslefree installation
The OEM 996 Turbo plenum with its Tshape causes the air flow from the throttle body to abruptly change direction when divided to each side of the intake manifolds Hence it's logical to consider a Yshape design to overcome this limitation The OEM 996 throttle body with a 68mm internal diameter has shown to be a bottleneck when operating at power levels above 700hp Consequently our performance plenum is designed to work in tandem with the 9971 throttle body which at 74mm is much better suited for higher power levels Please note that the 9971 throttle body is not included in this kit and must be purchased separately OEM part number 99760511500 After installing this part you will need to recalibrate the engine management software for optimal functionality
Throughout the development of this plenum considerable time was dedicated to flow simulations of the internal Yshape design We conducted both CAD system flow simulations and realworld tests on 3Dprinted models using our SuperFlow SF1020 flow bench
The do88 performance plenum is delivered as a comprehensive kit with all necessary parts for installation note the 9971 throttle body is not included
