T9351 DV+ Billet Aluminum Diverter Valve

The GoFastBits T9351 DV+ diverter valve offers a performance upgrade for factory diverter valves found in many Audi, VW, Skoda, and Porsche applications. This DV+ model retains the factory solenoid coil, which is highly effective due to its rapid ECU control, and replaces only the problematic plastic valve mechanism with a robust, anodized billet aluminum housing and a precisely machined brass piston. This construction ensures longevity and the ability to withstand higher boost levels, especially in modified or chipped engines. The DV+ utilizes a unique pilot-actuated valve mechanism, distinct from direct solenoid actuation. This system uses the solenoid to control air pressure, allowing the valve to open and close reliably regardless of boost pressure. This pilot actuation also enables progressive opening based on boost levels, leading to sharper throttle response and more efficient operation compared to standard valves that simply open or close fully. The product is CARB compliant and 50-state legal in the USA. No tune is needed if the system stays in recirculation mode.
