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
