The Vortex 6 air valve upgrade kit includes an upgraded VX6003 valve, 12 feet of 1/2" tubing, and necessary fittings and adapters to increase airflow into Kleinn horns. With a 1/2" NPT inlet and larger orifice, the kit raises sound output and helps make horns compatible with higher-pressure air systems by improving flow into each trumpet.
