Zawór blow off BOV Turbosmart TS-0203-1265 Kompact Plumb Back Ford Fiesta 1.0 Eco Boost - TS-0203-1265 - Turbosmart's new Kompact VR09 Plumb Back for the 1.0-litre Eco Boost is a billet 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 Eco Boost 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. The Kompact VR09 is precision machined, hand assembled and individually quality tested in Australia to the highest quality standards.
