Equip your vehicle with the Kleinn 141-1 direct bolt-on quad black air horn system, featuring four compact zinc alloy trumpets measuring 13 inches, 11 inches, 8.5 inches, and 7 inches in length with 3-inch bell ends to deliver devastating truck air horn sound in a space-saving design. Engineered for universal application and small enough to fit in almost any car, truck, or sport utility vehicle, this premium quad horn configuration is finished in Kleinn's exclusive XCR2.0 satin black corrosion-resistant coating to withstand the harshest environments while delivering a loud, full, and clean blast of up to 150.3 decibels at 150 PSI. The high-performance kit comes equipped with a heavy-duty Vortex 4 Series 12-volt electronic air horn solenoid valve to ensure instantaneous air delivery and an extreme train horn sound right out of the box. Designed for a clean, professional, and hassle-free installation, this complete package requires an onboard pressurized air system and combines a stealthy, durable black finish with maximum acoustic performance for builds with limited mounting space.
