ZERONINE Design FEN003AA charge pipe kit Ford Focus ST (Mk4, Mk4.5) 2.3 EcoBoost

The ZERONINE Design HVF (High Volume Flow) charge pipe upgrade kit for the Mk4 Focus ST removes multiple restrictions found in the OE air charge components, substantially improving airflow and reducing the pressure-drop across the charge system.

The OE components feature multiple complex sections which taper down or narrow in diameter by as much as 50% and uses a restrictive sound resonator section - all of which inhibit airflow and cause unwanted pressure buildup.

The ZERONINE Design HVF version has been carefully designed as a direct swap for the OE setup and is supplied with everything needed to help increase airflow by more than 60%.

Finished in a durable deep black anodised finish with matching black silicone hoses and jubilee clips, the HVF charge pipe is a must-have addition for those wanting to improve the performance and efficiency of their engine and to give a degree of headway to the turbocharger when optimising peak engine power and torque output.

Note:

• Our Charge Pipe Kit is designed to work in conjunction with the OEM recirculating valve. If you intend to fit an aftermarket BOV then please contact us first to confirm fitment.
• When installing this kit, you need to re-use the OE seal found in the standard upper hard pipe.
