Turbo tuning parts > Forge Blow off valves | FMDV9

This valve kit allows the fitment of a fast response blow off valve on the VW 1.0 TSi engine with the engine code PR-TJ4 found on Audi A1, Ibiza, Fabia and VW Polo. 

As the engine does not have a diverter valve fitted as standard, Forge Motorsport have developed a twin piston dump valve that not only gives you an incredibly loud sound when lifting off the throttle but it also increases the throttle response during gear changes by reducing turbo lag, it is designed to help the turbocharger maintain its rotational speed ready for when you accelerate.

This will not fit vehicles with the extra spout on the boost pipe as seen in the picture below. If your vehicle is as pictured below, FMDV18 will be compatible. 

This will not also fit to vehicles end 2021 and on, where engine may have some differences due to the map sensor placed on the front part of the boost pipe as shown at left picture bellow.
