Kleinn ProBlaster Model 141-1 Compact Quad Air Horn with 12V Solenoid, Black

The Kleinn ProBlaster Model 141-1 is a black compact quad air horn for trucks, SUVs, Jeeps and any other vehicle with onboard air. It's universal, and it's the replacement horn for Kleinn's HK4-1 black quad kit.

Four trumpets share a single manifold about 14" long, finished in Kleinn's black XCR 2.0 coating. A Vortex 4 (P/N 307) 12V solenoid comes pre-installed, and a small right-angle mounting bracket with hardware is in the box. Plumb it with 1/4" OD airline. Kleinn rates it at 150.3 dB at 150 PSI.

This horn suits blacked-out builds where you want more sound than stock but don't want chrome showing through the grille. It's small enough to fit behind most grilles or in the engine bay.

Horn and solenoid only. An air system that makes 120-150 PSI with at least a 0.5-gallon tank is required, along with airline and a horn button. Kleinn doesn't publish a model-specific install guide.

The chrome version is the Model 141. For a complete black kit with compressor and tank, look at the HK4-1. Covered by a 1-year limited warranty.
