Attention: This item is only suitable for vehicles with 1.2/ 1.4 TSI engine that do not have an original diverter valve. These can be recognized by the three intake ducts (marked in the picture below). If the engine compartment of your 1.2/1.4 TSI looks like this, this item is suitable.
The original valves already leak at the factory, causing a loss of power, which is even more pronounced in performance-enhanced vehicles due to the higher boost pressure.
The Audi, VW, Skoda and SEAT 1.2/1.4 TSI models from approx. year of manufacture 2014 onwards no longer have diverter valves installed ex works. This results in turbo surging during load changes (gear changes), which is not beneficial for the durability of the turbocharger.
GFB has a solution for this problem with the T9430 VTA valve: Excess boost pressure is released into the atmosphere via the valve during load changes, thus preventing turbo surging. In this way the turbocharger is protected and the valve produces the well-known blow off sound ("Whoosh").
Furthermore, these vehicles do not have a mass air flow sensor, so that the released air does not have a negative effect on the engine running.
Thanks to the sophisticated system, the T9430 can be installed plug and play in the charge air circuit by replacing a small plastic charge air pipe.
Attention: Open diverter valves/blow off valves are not legal in the German STVZO.
