GFB VTA BOV 2013+ Audi 1.2L/1.4L TFSI/TSI

The intake is acoustically tuned to surpress the fluttering sound of compressor surge, it does not eliminate the effect of pressure pulses- that is what diverter and Blow off valves were originally designed to do

The GFB T9430 re-introduces a blow-off valve into the 1.2/1.4 TSI system, which eliminates compressor surge to protect the turbo, and delivers the signature blow-off valve "whoosh" when liftingoff the throttle.

TMS Technology for faster boost recovery on gearshift and during throttle modulation •improved boost holding ability •Atmosphere venting for blow-off sound

These engines come from the factory with no diverter valve of any kind, resulting in turbo compressor surge every time the throttle is closed after boosting

Clips in with no tools required Blow-Off Valve Designed Specifically For Late-Model Audi, VW, Skoda, And SEAT 1.2 And 1.4TSI Models.
