GFB DV+ Diverter valve (Part number T9301) is a direct bolt on factory valve replacement. Designed to replace the weak plastic Bosch diverter valves commonly found on European applications like Audi, Ford and VW, but with the GFB TMS advantage.

The TMS range from GFB is designed specifically for the purpose of turbo lag reduction, and improving throttle response. Tests show TMS features can return engine to peak boost up to 30% faster than a factory diverter valve when shifting gears.

Unlike other aftermarket Bosch replacement valves on the market, the DV+ will hold as much boost as you can throw at it WITHOUT the need to adjust the spring pre-load or purchase different springs. This is because the pressure-balancing design of the DV+ means that under wide open throttle conditions there is equal boost pressure on both sides of the piston, so it will stay shut under boost REGARDLESS of the spring setting or the boost pressure.

These unique products are manufactured in Australia in accordance with ISO 9001 which ensures our products meet stringent quality requirements at all stages of manufacture.

Diverter valves, but with more!
GFB’s DV+ range is designed as a direct bolt-on replacement solution for problematic factory recirculating diverter valves. Not only do DV+ valves eliminate failure issues from high temperature and boost pressure, they also offer the TMS advantage of improved throttle response and boost holding.
