This Atmospheric Blow off Valve Spacer is for 2.0-liter TSI / TFSI engines. 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.

   The spacer is a great solution for open air venting, without converting over to a full blow off valve. Run it without worrying about a check engine light, as it is designed to circulate a certain amount of charge pressure to keep the engine running as it was from the factory.

   Simple in execution, yet offering the desirable atmospheric blow-off valve sound, this product has been designed to be fully compatible with the Bosch ME9 engine management systems employed on the following vehicles: Audi A3 2.0T FSI Audi B7/B8 A4 2.0T FSI Volkswagen MK5/MK6 Golf GTI/Jetta GLI 2.0T FSI.

NOTE: This part WILL fit ALL 2.0T FSi/TSi engines

Includes 3 bolts and washers for install.
