The OEM 996 Turbo plenum is T-shaped, meaning airflow from the throttle body abruptly changes direction as it's divided to each side of the intake manifold. It makes genuine sense to design a plenum with a Y-shape instead, and do88 took this further by engineering the design specifically to accept the later, larger 997.1 Turbo throttle body, a popular upgrade path for owners looking to increase airflow beyond the factory 996 spec.
Cast aluminium construction achieves the soft, sweeping shapes needed for optimal airflow, something CNC-machining simply cannot replicate, as do88 puts it, function always conquers form, maximum airflow supersedes the bling factor. CNC-machined connections and matched silicone hoses ensure optimum fitment and durability.
Please note: this plenum is specifically designed to accept the 997.1 Turbo throttle body, not the original 996 unit. Confirm you're planning this throttle body upgrade before ordering, or check with your supplier about fitment if you intend to retain your factory throttle body.
Why Choose This Plenum
Y-joint design, genuinely more efficient airflow distribution than the OE T-shape
Adapted specifically to accept the later 997.1 Turbo throttle body
