This pump features two important upgrades: This pump is engineered with VAC's famous Oil Pump Upgrade kit integrated in its design; this means a stronger gear drive mechanism for much lower likelihood of pump failures on the track. VAC has not only improved the physical reliability of the pump itself but also fit a custom gear with a larger sweep area to the pump mechanism, increasing volume by a welcome 22% An excellent upgrade for Road Race, Autocross, Time Attack, Drift, Hill Climb, Rally, Drag Race, Roll Race & forced induction applications. Lubrication issues are a common killer of BMW engines. The dual-pickup pump is much better than a standard single pickup, but this pump is a dramatic improvement over both.
