Want improved throttle response and increased ability to hold boost? Than it is time to replace the worn out factory diverter valve setup found in the 1.8T. Over time the OEM diverter valve will start to wear causing leaks. 

Go Fast Bits has developer their GFB DV+ T9301 diverter valve setup to solve that problem. Designed as a factory direct bolt on valve replacement, this unit is unlike other aftermarket bosch replacements on the market.

Tests have shown the GFB DV+ to return engine to peak boost up to 30% faster than the factory DV when shifting gears. Adding more boost to your car? Don't worry about leaks here as the GFB DV+ T9301 can handle as much boost as you can throw at it without the need to adjust the spring pre load or buy different springs. Why? The GFB DV+ has a pressure balancing design that during wide open throttle conditions is equal boost pressure on both sides of the piston, so it will stay shut under boost regardless of the spring setting or increased boost pressure.

Manufactured in Australia in accordance with ISO 9001 standards means the GFB DV+ T9301 meets strict quality requirements throughout all stages of the manufacturing process.
