Please make the answers simple for all of us. I understand Cx Racing owner from the german boost site said he's planning in making a CAI for our cars he has an X5d, we'll see what happens then
The only thing that comes to mind is that when you run the cone filter, you would be getting a consistent temperature/ pressure into engine without any serious fluctuations over the sensors. Running the box with a cold and warm intake and no vacuum control could result in variations across the sensors to produce a signal out of the limits set by BMW and trip to limp mode.
