TURBOSMART BOV KOMPACT SHORTIE DUAL PORT FORD MUSTANG 2015+No one knows EcoBoost better than Turbosmart. We make performance parts for every Ford EcoBoost application, but this is truly exciting, the worlds first aftermarket BOV for the new Mustang. Stock blow off valves like those that come standard with the Mustang often suffer from a range of problems. They are plastic, and they leak, and if you want to up the power (who doesnt?), they have trouble holding the extra boost.
