so NLP100290 are a no no for a wasted spark system?If your car has a wasted spark system (two coil packs at the top of the engine, under the cover, no distributor), you might be better off with the standard NGK BKR6E. If you want platinum then NGK PFR6N-11 (longer service life).
However the NGK Iridium has a small centre electrode, and will be very similar to the problems of the NLP100290.
For a wasted spark system, the ultimate spark plug will be a double-platinum or double iridium electrode.
