The OEM 997 Turbo plenum is T-shaped which means the air flow from the throttle body abruptly change direction when it´s divided to each side of the intake manifolds. It makes sense to design a plenum with a Y-shape instead of a “bank into the wall” T-shape.

During the development process of this plenum we spent a lot of time with flow simulations of the internal Y-shape design. We made both flow simulations on our CAD system and real tests on our own SuperFlow SF-1020 flow bench on 3D-printed models.

The results of the final design were very impressive the do88 Plenum totally outperform the OEM Plenum by 34% increased flow at the same pressure drop!

To be able to manufacture this final design we choose to make a 3D freeform designed casting. This construction adds a lot of performance but not so much of extra weight. We designed the outside of the plenum to add as little weight as possible to the plenum.
do88 Performance Plenum weight 0,80 kg (1,76 lb) OEM plastic pipe weight 0,28 kg (0,62 lb) and competitor cast performance pipe weight 1,19kg (2,63 lb)!


- do88 plenum is Y-shaped for improved air flow. Our plenum flows 34% better linked to the GT3 throttle body, compared with the OEM plenum
- High quality casting pipe with CNC-machined connections
- Smooth internal surface for best air flow
- Comes with all necessary accessories for installation
