Intake & Oil Issues

So my last car was a modified G35 and there were always discussions about aftermarket intake filters improving the performance on the VQ engine, but a downside was that oil from the aftermarket filters would get sucked through the manifold and eventually decrease performance. It seems on the N54 that most people go the route of an aftermarket oiled filter (whether cones or drop-in), but I have yet to find any discussion on the topic of whether this additional oil being sucked through further decreases performance? I know there is already oil coming through on these engines as I have seen it myself on my car, but I just wanted to see if topic has been brought up?
