GFB VTA T9468 blow-off valve Ford Focus ST Mk.4 280hp, Mustang 2.3L Ecoboost (GFBDVT9468)

The VTA valve T9468 with the advantages of a closed DV+ valve AND blow-off valve sound! The VTA valve has the same design as a closed DV+ - and therefore the same advantages - but also has an opening so that excess charge air can escape to the atmosphere and produce the familiar blow-off sound. The original valves already leak straight from the factory, which causes a loss of power that is even more pronounced on tuned vehicles because of the higher boost pressure. Installing the GFB DV+/VTA closes this “hole” in the charge-air system and thereby noticeably improves response and boost retention. In addition, the turbocharger is protected, as it no longer has to work “against” the hole in the charge-air system. At the same time, the well-known “whoosh” sound is produced when changing gear, as excess charge air is vented to the atmosphere. Other manufacturers offer a simple spacer to produce the blow-off sound, which is also fitted under the original valve. Although this produces a blow-off sound, it does not solve the problem of the leaking original valve. With the GFB VTA valve, both problems are eliminated in one go! Open diverter valves / blow-off valves are not road-legal under the German StVZO.
