The Turbosmart Kompact EM plumb-back diverter valve for 2015–2021 Volkswagen GTI and Golf R MK7 is a plug-and-play unit that replaces the OEM diverter valve without adapters. The Kompact EM maintains OE electronic control while reducing leakage and improving thermal response; the plumb-back version vents back into the intake, matching the original diverter routing for those model years.
