VTT Is proud to offer the Turbosmart Kompact EM BOV VR1, in both Dual-Port and Plumb Back.

For the Dual-Port they are a 50/50 DV meaning they vent the first 50% of travel back into the intake, and the last 50% of travel is VTA.

The Plumb Back functions exactly like the factory DV venting all bypassed air back into the intake, but with improved response and venting capability.

A must-have for hybrid or larger flowing turbos that utilize OE electronic diverter valve by not leaking, the EM will achieve target boost without stressing the turbocharger and wastegatePlumb back vents back into the air intake.
