aluminium replacement for the Fiesta's factory plastic BOV.
The Plumb Back is a full recirculating valve for quieter operation and OEM-style operation,
with all the performance benefits of a Turbosmart BOV.
The standard bypass valve on the 1.0-litre EcoBoost engines is a weak, plastic,
diaphragm-type valve - a type of valve that has a track record of failures. Turbosmart's
billet aluminium replacement is manufactured with precision, designed for unlimited
boost holding capability, excellent response times and heavy-duty reliability.
Installation is straightforward, and the valve is a bolt-on direct replacement for the factory
valve. No special tools are required and all necessary hardware is included.
