Go Fast Bits High Quality DV+ Diverter Valve System for 2017-2019 Ford Focus RS GFB's DV+ diverter valve range offers a direct-fit performance solution for the weak factory diverter valves used on many modern vehicles. By retaining the factory ECU control and recirculating the vented air, the DV+ is a purely performance-orientated product. GFB’s DV+ design solves the longevity and boost leaking issues that are common with factory diverter valves, and also changes the operation method to “pilot actuation” to ensure better performance on stock or modified engines.
