I agree with all of you WRT PL14610. Probably no harm no foul. It would be a prick move on Nissan's part but look what happened in another post in this thread. A poster called the dealer and mentioned Purolator and they weren't too receptive to that idea.
so one could only surmise they could be all over a wrong part number given an opportunity. Until mine is out of warranty or I trade for a C7 I'm using what is specified, M-108's, OEM and PL14612's.
