N55 GFB DV+ Upgrade

Retains the factory solenoid coil for seamless integration -Replaces plastic valve parts with metal for reliability and strength on chipped engines -Direct-fit replacement -Exclusive “pilot-actuated” valve mechanism for rapid response at high boost -The DV+ range with a direct-fit solution for the weak factory diverter valve used on many European vehicles. The solenoid coil itself from the factory-fitted valve is great (the ECU opens it faster than any pneumatic valve so why replace it?), but the weak point however is the valve mechanism itself. So the DV+ solves this problem by replacing just the valve parts with an anodized billet aluminium housing fitted with a brass piston machined to exacting tolerances. The end result is sharper throttle response, lightning-fast valve actuation, and it will hold as much boost as you can throw at it.
