We’re pleased to introduce our custom-built plenum, designed specifically for the Porsche 911 (996) Turbo. This high-flow plenum is designed to significantly improve the performance of your 996 Turbo!
Key Features:
Designed to work with the 997.1 Turbo throttle body (part number 99760511500) to address the airflow restrictions of the OEM 996 throttle body.
Includes two silicone hoses for compatibility with both the high-performance DO88 Y-pipe (TR-360) and the OEM Y-pipe.
Made of high-quality cast tubing with precision CNC-machined connections.
Smooth internal surface for optimal airflow.
Comes with all necessary hardware for a hassle-free installation.
The OEM 996 Turbo plenum, with its T-shape, causes airflow from the throttle body to abruptly change direction when split on each side of the intake manifolds. Therefore, it makes sense to consider a Y-shaped design to overcome this limitation. The OEM 996 throttle body, with an internal diameter of 68 mm, has proven to be a bottleneck when operating at power levels above 700 hp. Consequently, our performance plenum is designed to work in tandem with the 997.1 throttle body, which at 74 mm is much better suited for higher power levels. Please note that the 997.1 throttle body is not included in this kit and must be purchased separately (original part number 99760511500). After installing this part, you will need to recalibrate your engine management software for optimal functionality.
During the development of this plenum, considerable time was spent on flow simulations of the Y-shaped internal design. We conducted both CAD system flow simulations and real-world testing on 3D printed models using our SuperFlow SF-1020 flow bench.
The do88 performance plenum comes as a complete kit with all the necessary parts for installation (note: the 997.1 throttle body is not included).
