Direct bolt on without worry of a check-engine light
This Atmospheric Blow-off Valve Spacer from AGR is a first of its kind for the 1.4 / 1.8 / 2.0 for TSI/TFSI Turbo engines only. The spacer is a pressure release system that can be used with the stock diverter valve to vent extra boost air into the atmosphere instead of sending it back into the engine's intake piping.
