Although the various 1.5 TSI engines share many of the same components the later engines have a slightly different configuration, please remove your engine cover to establish what kit is needed.

As the engine does not have a diverter valve fitted as standard, Forge have developed a twin piston dump valve that not only gives you an incredibly loud sound when lifting off the throttle, but also increases the throttle response during gear changes by reducing turbo lag. It has been designed to help the turbocharger maintain its rotational speed ready for when you accelerate, whilst also taking the strain away from the impeller. Without removing this stress from your turbo, it could cause premature failure. Especially on engines and modified vehicles.


The Forge valve kit allows the fitment of the fast response blow off valve preventing turbo surge and prolonging the life of your engine’s turbocharger.

The kit includes all of the necessary hardware and step by step installation instructions for any car enthusiast with appropriate garage tools to fit at home, in just a couple of hours!

Due to the exposed position of the OEM boost pipe and the nature of the heat cycle, the plastic that the OEM pipe is made from can deteriorate over time, becoming brittle and susceptible to boost leaks. This kit totally replaces this plastic pipe from turbo to manifold with a silicone hose (available in a choice of colours!).

  • Forge valve will not bring on any check engine lights (EML)
