No one knows EcoBoost better than Turbosmart. We make performance parts for every Ford EcoBoost application, but this, the world’s first aftermarket BOV for the new Fiesta ST is truly exciting.
Stock blow-off valves like those that come standard with the Fiesta ST often suffer from a range of problems. They are plastic, and they leak, and if you want to up the power (who doesn't?) they have trouble holding the extra boost.
