Full Mechanical BOV conversion
Please note that this is NOT comparable to the BOV adaptors/Spacers that use the factory electronic valve.
This unit completely replaces the leak-prone factory ECU controlled valves (or blank plate on older models) 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.
