Dual Port BOV for the twin turbo BMW.
Goodspeed is now offering our Forge Splitter Direct Fit diverter valves for the twin turbo BMWs; 135i, 335i, 535i and Z4.

This is a GoodSpeed exclusive set allowing the use of a true dual port diverter valve to be used with a OEM fit.
Using this valve allows the owner the ability to have infinite adjustability for whatever boost level they are running, and it can be run as a full recirculation or atmosphere. This kit is the perfect option for the weak Bosch units and we recommend it for any stage of performance.
