BOV Kompact EM Dual port VR22 - Ford Fiesta ST
The Turbosmart Kompact EM Dual Port VR22 is a premium, motorsport-proven electronic blow-off valve designed as a direct plug-and-play upgrade for your factory electronic diverter system. Built from rugged billet aluminum and featuring Turbosmart’s unique Boost-Balance valve technology, it is guaranteed not to leak boost pressure, making it an essential upgrade for tuned, hybrid, or big-turbo builds. The Dual Port configuration splits air management perfectly, venting back into the intake for OE computer compatibility while releasing an aggressive atmospheric blow-off sound.
Take Total Control of Your Boost with Factory Integration
The award-winning Turbosmart Kompact EM (Electro-Mechanical) Series represents the world's first truly plug-and-play upgrade solution for your factory electronic diverter valve . Designed specifically to overcome the structural weaknesses of flimsy plastic OEM valves, the VR22 variant drops straight into your setup with zero modifications, vacuum lines, adapters, or external solenoids required . Simply unbolt your factory unit, install the Kompact EM in its place, and plug the factory connector straight in .
Dual Port Versatility & Sound
The Dual Port configuration gives you the best of both worlds . It features split operation—venting air back into the intake system to keep the factory ECU happy, while simultaneously discharging excess boost pressure directly to the atmosphere to give you that iconic, crisp motorsport blow-off sound .
Motorsport-Grade Construction & Boost-Balance Design
Machined out of hand-assembled billet aluminum and equipped with high-temperature Viton O-rings, this valve is engineered to endure brutal boost levels and intense thermal environments . Featuring Turbosmart’s revolutionary Boost-Balance Valve Design, the internal piston relies on pressure differentials rather than heavy spring tension . This means the more boost you push through your turbocharger, the tighter the valve seals against its seat —guaranteeing zero boost leaks even on highly modified hybrid or large-frame turbo upgrades .
