Y-CHARGE PIPE KIT PORSCHE 991.2 TURBO (S) Item no.: 001100006-KIT High Performance Y-charge pipe for Porsche 991.2 Turbo(S) This unique Y-charge pipe has been designed for the best possible internal airflow, while using laborious CFD simulation. All bottlenecks of the stock mounted Y-charge pipe were eliminated and adapted to a uniform cross-section. This means, the intake air is no longer unnecessarily blocked by cross-sectional changes and results in a reduction of the pressure drop inside the charge air system. For your vehicle, this manifests itself in a noticeable increase in performance (depending on the software version).
