Description
Full Mechanical BOV conversion for W176 A45 (and variants)
Please note that this is NOT comparable to VTAs or adaptors that still use the factory valves.
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 those with stage 2 and higher tunes where the factory valves can no longer support higher boost levels.
