Why does my 1.2L or 1.4L TSI engine need a blow-off valve?

Your engine from the factory lacks a diverter or blow-off valve. When you close the throttle after building boost, this can cause compressor surge, which puts stress on the turbo. This valve reintroduces that protection and also provides the characteristic blow-off sound.

How difficult is the installation for this blow-off valve?

The Go Fast Bits T9430 is designed to clip into place on your vehicle's existing plumbing. No special tools are required, making it a straightforward installation.

What does TMS Technology do?

TMS Technology in this blow-off valve helps improve how the engine holds boost. It also aids in faster boost recovery, especially during gearshifts and when you modulate the throttle.
