GFB VTA Blow Off Valve Kit with Whistling Trumpet - Alfa Romeo Giulia / Stelvio Quadrifoglio 2016+ - Pair

This kit replaces both factory diverter valves on the 2.9 litre twin turbo V6 with GFB VTA valves, venting charge air to atmosphere for the audible blow off note the factory valves recirculate away. Each valve keeps its integrated solenoid so it stays plug and play with the factory ECU signal, and the pilot operated piston opens and closes progressively instead of snapping shut, which holds boost response while tolerating up to 50 psi. Spring preload is adjustable to set how early the valve releases. The Whistling Trumpet screws off if you prefer a softer whoosh to the whistle.
