Turbosmart Kompact EM VR17 Dual Port BOV – Toyota GR Yaris, GR Corolla

The Turbosmart Kompact EM Series of upgraded diverter valves is the world’s first genuine plug-and-play upgrade solution for factory diverter valves. Specifically designed for vehicles such as the Toyota GR Yaris and GR Corolla, this valve offers a direct-fit replacement that requires no adaptors, hoses, or additional assembly—just unplug the factory valve, unbolt it, and install the Kompact EM.

Built on motorsport-proven billet valve technology, the Kompact EM Series features an integrated proprietary solenoid and internal pressure control channels for seamless OE electronic integration. With no reference hoses, separate solenoids, or external components required, installation is simple and clean.

The Kompact EM Series resolves the common issues found in plastic OEM valves by utilising Boost-Balance Valve design, a positive-sealing face O-ring, and billet aluminium construction. The result is improved durability, boost control, and responsiveness, whether on the road or track.
