Go Fast Bits offers DV Plus Diverter Valves with TMS (Turbo Management System) Advantage for a wide range of vehicles, particularly imports. GFB's DV+ solution couldn't be simpler—keep what works and replace what doesn't. GFB expands 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 is the valve mechanism itself. So GFB's DV+ solves this problem by replacing just the valve parts with an anodized billet aluminum 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. Other manufacturers' products involve replacing the entire system with a traditional pneumatic valve, requiring long vacuum hose runs, additional parts for tapping into the intake manifold vacuum—plus either a different solenoid valve to actuate the pneumatic valve, or a ballast resistor to plug into the OE wiring loom. All these additional items result in a product that is slower, less responsive, more expensive and takes much longer to install. GFB's DV+ solution on the other hand is more responsive, less expensive, easier to install, and doesn't cause compressor surge/turbo flutter. Order the model recommended for your vehicle. Additional notes: * Retains the factory solenoid coil for seamless integration * Replaces plastic valve parts with metal for reliability and strength on chipped engines * Exclusive "pilot-actuated" valve mechanism for rapid response at high boost

Other manufacturers' products involve replacing the entire system with a traditional pneumatic valve, or include a solenoid valve with the diverter. These approaches add unnecessary cost and additional parts (in some cases requiring long vacuum hose runs, mounting brackets, etc.). All these additional items result in a product that is slower, less responsive, more expensive, and takes longer to install. GFB's DV+ solution, on the other hand, is more responsive, less expensive, easier to install, and doesn't cause compressor surge/turbo flutter. Oh, and it doesn't require different springs or frequent re-builds, either. Order the model recommended for your vehicle.

Crown Automotive exhaust check valves prevent exhaust from forcing its way back through the air injection system, which would damage the pump and other components. If your original parts are bad, they will be unable to sense the increase in the intake manifold vacuum and may cause damage to the cylinder head, pistons, and cylinder bores.
