Abstract: A self tapping spray nozzle for use in a vehicle ventilation system is preferably made of stainless steel. The spray nozzle has a neck with an internal channel and threads cut into its outside surface. A wedge at a thirty degree angle, having sharpened edges is at the top of the neck. At least one port extends from the channel to the outside surface of the neck. A collar with a plurality of sides encompasses the circumference of the neck at its bottom. One side of the collar is aligned with the port to help align the port in a desired direction.
