Soft spring for the T9354 and T9360 DV+ valves, intended for use in vehicles without a vacuum pump.
The standard spring supplied with the T9354 and T9360 DV+ valves is designed for vehicles with a vacuum pump, such as the Ford Focus ST and Focus RS, which provide a strong vacuum signal. In vehicles without a vacuum pump, such as the Opel Astra, the vacuum signal is weaker, so the DV+ valve may have difficulty opening fully.
In such cases, the GFB 6114 spring enables the diverter valve to operate correctly.
