GFB VTA T9468 blow off valve Ford Focus ST Mk.4 280HP, Mustang 2.3L Ecoboost

The VTA valve T9468 with the advantages of a closed DV+ valve AND Blow Off Valve Sound!

The VTA valve has the same construction as a closed DV+ - so also the same advantages - but additionally an opening so that the excess charge air can escape into the atmosphere and thus produces the well-known blow off sound.

The original valves are already leaking from the factory, which causes a loss of power that is even more pronounced in performance-enhanced vehicles due to the higher boost pressure.

By installing the GFB DV+/VTA, this "hole" in the charge air system is closed and in this way the response behaviour and the retention of the charge pressure is noticeably improved.
In addition, the turbocharger is protected because 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 during the gearshift by releasing excess charge air into the atmosphere.
Other manufacturers offer a simple spacer to generate the blow-off sound, which is also installed under the original valve.
This produces a blow off sound, but does not solve the problem of the leaky original valve.
With the GFB VTA valve, both problems are eliminated at once!

Open diverter valves/blow off valves are not legal in the German STVZO.
