Cotton filter for the blow-off valve of the 1.4 Turbo engine in the 500, 595, Grande Punto Abarth, and Alfa Romeo 1.4 T-Jet.
This filter is easily installed on the turbine pressure outlet hose and transforms the original blow-off valve into an open vent.
This allows you to hear the characteristic "whoosh" sound when releasing the throttle, typical of Abarth vehicles.
The kit includes a blue or red silicone cap to be applied to the horizontal pipe (rail) to complete the installation.
This installation does not require any electronic or mechanical modifications, as it replaces the rubber hose on the turbine pressure outlet, and the cap fits into the open hole of the air filter.
