Review on 🔊 Enhance Your Vehicle's Impact with Kleinn Air Horns 99 - Chrome-Plated Zinc Alloy Dual Air Horn by Mike Barnes

this horn is very loud. high tone. best sound at 90psi. I installed 4 in my other car so 4 times the volume is crazy. Uses 1/4" air supply and 12 volts to the solenoid. On this new setup I removed the solenoid and installed a 3/8" air line fitting with a 3/8" remote controlled solenoid. Sound improved. This horn is a lot fuller and draws people's attention.3 gallon air supply capacity is the minimum.
