A switchable spacer for the VAG 2.0 litre FSi Turbo engine which allows a choice of Blow off (loud) / Blow off and partial recirculation (intermediate) or total recirculation (quiet). This gives you the choice of exactly how loud you wish your valve to be .
NOTE: Due to clearance issues the adjustable FMFSiTA valve will NOT work on the Audi A4 or the new VW/Audi TSi engine or any 2.0T with the revised ”D” version diverter vavle installed - please use the FMDV14T for these vehicles.
