Adjustable Boost-Operated Bypass Valve for Ford Fiesta ST (2014–2019) – CNC Billet Recirculating BPV for USDM MAP & EU MAF Tuned Vehicles (Red)

Adjustable Boost-Operated Bypass Valve for Ford Fiesta ST (2014–2019) – CNC Billet Recirculating BPV for USDM MAP & EU MAF Tuned Vehicles (Red)

• Engineered for 2014–2019 Fiesta ST: Direct replacement for the weak OEM bypass valve, providing stronger, leak-free performance on all model years.
• USDM & EU Compatible: Works flawlessly on both MAP-tuned U.S. vehicles and MAF-tuned European models—100% safe for all tuning setups.
• Quiet, Recirculated Operation: Functions as a vent-to-intake BPV for drivers who want added performance without the loud VTA blow-off sound.
• Boost-Operated Design: ECU-controlled solenoid provides both boost and vacuum; boost pressure keeps the valve sealed under load while vacuum ensures consistent opening.
• Prevents Flutter & Surging: Eliminates premature valve opening, pressure spikes, and turbo flutter, helping maintain steady boost and reduce turbo lag.
• Built to Last: CNC-machined from billet aluminum with an internal brass piston and pressure-tested to 75 PSI, this plug-and-play valve installs easily using the included hardware and factory-style solenoid connector. Designed and manufactured 100% in-house in the USA.
