Increase air flow and push the model 730 train horn demon to unheard of decibel levels. Provides everything needed to add an additional two solenoid valves to model 730 train horn demon.

Very nice upgrade 👍
This is a must have for the Demon kit. Super loud and very happy with it.Run three individual hot wires and grounds, take the three hots and fix together to a larger gauge to run to the battery. Same for the grounds and put it to the frame. Piece of cake.

Not everything was included and the threads don’t match...
Looks like a great kit - but it's not. The threads on the adapters in this kit aren't the same as the threads on the horns. I also didn't receive everything that is in the picture.The instructions could use a little more work as well.The valves stick closed when the tank is fully pressurized - which makes it sound like a tricycle horn...
