Full Mechanical BOV conversion for all 4 litre Biturbo M177 engines
Please note that this is NOT comparable to the gimmick BOV adaptors sold by some.
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.
