1. A fuel injector nozzle comprising:
a non-coined three-dimensional inlet face comprising a first inlet surface and a second inlet surface, with said inlet face not being formed by a deformation process; an outlet face opposite said inlet face; and one or more first nozzle through-holes and one or more second nozzle through-holes, with each said first nozzle through-hole comprising at least one inlet opening on said first inlet surface connected to at least one outlet opening on said outlet face by a cavity defined by an interior surface, and each said second nozzle through-hole comprising at least one inlet opening on said second inlet surface connected to at least one outlet opening on said outlet face by a cavity defined by an interior surface, wherein said first inlet surface is not coplanar with said second inlet surface.
