Turbosmart Kompact EM VR17 Plumb Back BOV – Toyota GR Yaris, GR Corolla

The Turbosmart Kompact EM Series of upgraded diverter valves is the world’s first true plug-and-play solution for factory diverter valve replacement. Designed specifically for modern performance vehicles like the Toyota GR Yaris and GR Corolla, this valve installs easily with no adaptors, hoses, or additional components required—simply unplug and unbolt the OEM valve and install the Kompact EM unit in its place.

Using motorsport-proven billet valve construction, the Kompact EM Series integrates a proprietary high-temperature solenoid and internal pressure control channels for complete OE electronic compatibility. There are no reference hoses or external solenoids—just a compact, efficient solution with full electronic control.

The valve design addresses the common weaknesses of plastic factory diverter valves by incorporating Boost-Balance Valve Technology, a face-sealing O-ring, and a precision-machined billet aluminium body. The result is improved sealing, greater durability under boost, and long-term reliability across both street and track applications.
