Review on 🔊 Chrome Kleinn Air Horns HK2 Complete Dual Truck Air Horn Package by Terrance Haralson

I bought this to replace a factory horn that died on my truck. It took a good 4 hours of fiddling to get it working. I installed the compressor under the driver's cab on the passenger side. It's quite noisy until the tank is full in just 45 seconds. When I turn on my truck, the compressor turns on for less than a minute and is ready to go. If I honk the horn for about 4 seconds while driving, the supercharger will turn on when I release the horn to fill up the tank. Noise does not bother us in the short operating time. The noise of this thing definitely draws attention. I regularly make people jump up and down in traffic. Sounds like a train or half a whistle. I love this purchase!
