Here are the Dyno figures after swapping out the original manifold for the 3 stage.

My setup is a 2006 3.0i (N52), 3 stage intake manifold, K&N high-flow drop in filter with air-box charcoal filter delete (No ECU tuning yet) - Best run was 191.0 hp / 176.0 ft/Ls torque (add 20% loss according to the Dyno guy) and that puts me at 229.2 HP
