It is no secret that the Yaris GR is a high-performance hatch-back stomping onto the scene. However, we have found that at increased boost pressure, the OEM BOV struggles and ends up bleeding boost, resulting in a loss of power. Turbosmart has an answer to this problem. The BOV Kompact EM Plumb Back. This Blow-off valve has superior boost control under high boost pressure. This means that the turbo reaches its full potential! Not only does the Plumb Back BOV increase the performance of the turbo it also adds that Crisp.

Not satisfied with how your turbo sounds on your Toyota Yaris GR? Turbosmart has designed the BOV Kompact Dual Port to make your car sound like the awesome rally car it is. As well the OEM BOV is prone to boost bleeding as it struggles to cope with high boost pressure. The Turbosmart Dual Port blow-off valve holds the boost better at increased pressure allowing your turbo to perform to the best of its ability!

The award-winning Kompact EM series Blow-Off Valves, are the world’s first truly plug-and-play Blow-Off Valves. Simply unplug and unbolt your OEM Blow-Off Valve, and install ours in its place. No adapters, hoses, or extra assembly required. All this while retaining complete OE control of the BOV’s operation. Turbocharger performance is increased due to minimising leakage, rapid response, coupled with superior thermal performance thanks to our world-leading engineering and simulation abilities. A must-have for hybrid or larger flowing turbos that utilise OE electronic diverter valve by not leaking, the EM will achieve target boost without stressing the turbocharger and wastegate.
