09 Design HVF Rear Crossover Pipe Kit – Ford Fiesta ST Mk8/8.5 / Ford Puma ST
Unlock smoother intake flow and cooler running with the 09 Design HVF (High Volume Flow) rear crossover pipe kit. Designed for the Fiesta ST Mk8/8.5 and Puma ST, it replaces the restrictive rear intake section to help the turbo breathe more freely.
The large-bore, mandrel-bent aluminium pipe reduces pressure drop across the intake. This means the turbo can spool with less effort, helping throttle response and consistency. A high-performance thermal blanket is included to limit heat soak near the turbo, keeping intake air temperatures more stable in traffic and on spirited drives.
The kit comes ready to fit with a silicone coupler and quality hose clips. The anodised black finish looks factory-smart and resists corrosion. It is also an ideal match for the 09 Design carbon induction kit if you want to optimise the whole intake path.
- Smoother airflow and reduced restriction
