ZERONINE Design HVF Charge Pipe Kit – Ford Focus ST Mk4/Mk4.5

09 Design HVF Charge Pipe Kit – Ford Focus ST Mk4/Mk4.5 The 09 Design HVF (High Volume Flow) charge pipe kit replaces restrictive factory pipework on the Focus ST Mk4 and Mk4.5. It removes narrow sections and the OE sound resonator that choke airflow and cause pressure build-up. The result is smoother, higher volume flow and a noticeable drop in pressure loss across the charge system. The OE setup can taper by up to 50% in places. This kit uses a high-flow layout to open up the system and can improve airflow by more than 60%. That helps the turbo work more efficiently, supports stable boost, and can aid power and torque when tuning. Each hard pipe is finished in a durable deep black anodised coating. It is supplied with matching black silicone hoses and quality jubilee clips for a clean, factory-like fit. It is a direct swap for the OE parts and retains the OEM recirculating valve for reliable operation. Smoother, higher volume airflow for improved response Reduced pressure drop through the charge system Direct-fit kit with black anodised hard pipes and silicone hoses Fitment Designed for Ford Focus ST Mk4 and Mk4.5 models. Use our vehicle lookup to confirm fitment, or check the Vehicle Fitment tab for full details. Compatibility notes Works with the OEM recirculating valve. If planning an aftermarket blow-off valve, confirm compatibility in the Vehicle Fitment tab before purchase. Installation notes Re-use the OE seal from the standard upper hard pipe during installation. Professional fitting is recommended if you are unsure. This upgrade focuses on airflow efficiency and reliability. Expect crisper throttle response and more consistent boost, especially on tuned cars, without adding unnecessary noise.
