An air nozzle for blowing water off a vehicle moving through a car wash comprises a unit nozzle housing of molded plastic material having opposed front and rear walls and a side wall, with the front and rear walls terminating in opposed concave converging sides defining a lateral nozzle having a series of elongated throated orifices. The walls and sides define an elongated air chamber communicating with the orifices. An air inlet at one end of the housing is a part thereof and is adapted to receive a flexible hose connected to a pressurized air source. The front and rear walls have molded therein spaced mount plates or pads adapted for connection to a support arm and to a sensor respectively. A plurality of spaced threaded insert fasteners are molded, interlocked and enclosed selectively within one of the front and rear walls and the corresponding mount pads. The method of making a unit nozzle housing of molded plastic material is also disclosed.
