It's not plug and play though with the N54 and I'm sure it would be the same for the N55. There are threads on E90 post where people found the proper gap to run them on the N54, but I haven't seen anything for the N55. I'm sure someone could get them to work on the N55 you'd just have to be willing to experiment a bit with the gap.
