GFB VTA Diverter Valve w/Integrated Solenoid

Upgrade your Fiat or Alfa Romeo with the GFB VTA Diverter Valve featuring an integrated solenoid. This high-performance blow-off valve allows for a tailored venting experience, giving you the ability to choose between a traditional "whoosh" sound or an eye-catching whistle that stands out in the Euro scene.

Customise your auditory experience with the added benefit of adjustable spring pre-load. This feature enables you to control the timing and duration of the blow-off action. A lighter pre-load results in a longer release at lower engine loads, while a firmer setting restricts it to higher engine loads, offering you flexibility based on your driving style.

Designed for low-profile installation, the valve’s streamlined configuration means it fits easily even in tight spaces, perfect for modern aftermarket intakes. Check your vehicle against our fitment list to ensure compatibility. If you encounter multiple valve options, refer to our guide to find which one aligns best with your requirements.

WHY FIT A VTA?

Uncompromised Throttle Response

Modern OEM electronic diverter valves might be faster than pneumatic types, but they are binary in operation – open or shut. What they gain in operational speed, they lose in throttle response. The VTA adapts the method of operation of the factory diverter system to give you the best of both worlds. Pilot Operation – the patented design of the VTA means the piston is not directly connected to the solenoid, so it can open and shut progressively. This operation method leads to improved throttle response and drivability, because the VTA is more “discerning” about how much air it vents when triggered by the ECU – it only vents the amount of air necessary to eliminate pressure spikes that cause compressor surge, where the factory diverter opens fully whether it needs to or not. When you close the throttle during spirited driving, the VTA opens to prevent compressor surge and protect the turbo. When the pressure has dropped sufficiently, the piston begins closing to preserve a small amount of boost in the intercooler for as long as possible. This helps the turbo return to peak boost faster when you re-open the throttle. We call this the Turbo Management System (TMS) benefit.

Sharper throttle response, faster boost recovery after throttle lift

Choose Your Sound: With the removable extended trumpet, you can configure the T9416 to give you either a classic “whoosh”, or the loudest, most unique whistle sound you’ve ever heard!

Customise Your Sound: also featuring adjustable spring pre-load so you can fine tune when it blows off, and for how long. A softer pre-load allows the valve to blow off for longer and at lower engine loads. If you prefer to hear it only at higher engine loads you can use a firmer pre-load. Low-Profile,

Easy Installation: Using our integrated solenoid design stacked in an “over/under” configuration, the super-low profile allows clean and simple fitment in the factory location.

WHY CHOOSE A VTA?

Hold My Boost And Watch This…

Your turbo works hard to create boost, so why make it work harder than it needs to? A GFB VTA ensures that all your hard-earned boost makes it to the engine. Unsurprisingly, the moulded plastic valve components in the factory electronic diverter valve don’t seal that well. The VTA replaces the factory diverter’s loose-fitting plastic valve with precision CNC machined metal components and a durable elastomer piston seal. Because the VTA design uses boost pressure to force the piston shut, it doesn’t matter how much boost you throw at it.
