A vapor generator is in communication with a first portion of the air passage, where the vapor generator is configured to communicate the pre-vapor formulation from the reservoir to the first portion and at least partially vaporize the pre-vapor formulation. A first air inlet is defined by the cartridge, where the first air inlet is in communication with a second portion of the air passage, the second portion being upstream of the vapor generator. A dilution air passage is defined by the cartridge, where a discharge end of the dilution air passage intersect a third portion of the air passage that is downstream of the vapor generator. The method makes the cartridge. The e-vaping device includes the cartridge.
