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.
The required gap correlated to the power your running. If you running stock turbo's then a stock type gap should work. I think the N54's were lowering gap from .028 to .022 which again is only needed at higher boost levels with upgraded turbo's when you start to misfire.
