This unit completely replaces the leak-prone factory ECU controlled valves with a purely mechanical valve that is only controlled by boost & manifold pressure. An essential upgrade for up to stage 2 tunes, where the factory valves can no longer support higher boost levels.
NOTE: The Kompact valve is limited in spring pressure and flow volume. For cars higher than "stage 2" (with upgraded turbos) we suggest our RPA conversion.
Genuine Turbosmart Kompact blow off valves
Increased boost capability up to "stage 2" or ZAC OPTIMUM SILVER tunes
Eliminates leak-prone factory valve all together.
Adjustable spring pressure, allowing changes to actuation of valve.
