Upgrading boost or the turbo will reveal deficiencies in other areas of the engine. On the N55 engine one of the first weak areas is the factory electric diverter valve. This GFB Diverter Valve is much more robust than the factory piece and is essential when making more boost. It's a direct replacement on the electrical solenoid on the N55 turbo used on 2011+ E82 135i, F22 M235i, E90/E92 and F30 335i, F32 435i, F10 535i, F25 X3 35i, F26 X4 35i, E70 and F15 X5 35i, and E71/F16 X6 35i.

The Diverter Valve (DV) helps regulate boost on the N55 engine. Instead of releasing overboosted air into the atmosphere (like on a blow-off valve) the DV redirects the overboost back through the turbo. It's an efficient and tight system that minimizes emissions and reduces components under the hood. The problems with the factory DV are two-fold: the plastic housing can break and create a boost loss and the spring and diaphragm are just too weak to hold up to increased pressures (either by design or by accident).

This Go Fast Bits (GFB) DV+ design is much stronger thanks to an aluminum housing and with a more robust internal spring and diaphragm. The DV+ is still actuated by the stock factory electrical solenoid which is still managed by the engine computer. So it still functions just like a stock DV but with better reliability, especially with more boost. Throttle response is also improved.

Fits 2011+ models with N55 single-turbo engine only.
