Zawór blow off BOV Turbosmart TS-0203-1065 Kompact Dual Port Ford Fiesta 1.0 Eco Boost - TS-0203-1065 - Turbosmart's new Kompact VR09 Dual Port for the 1.0-litre Eco Boost is a billet aluminium replacement for the Fiesta's factory plastic BOV. The Dual Port is a 50-50 recirculation/vent-to-atmosphere valve for that classic vent-to-atmosphere BOV sound at high boost, and quiet operation at low boost. 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.
