Model HK4: Universal ProBlaster™ Chrome Quad Air Horn System
STOP BEING IGNORED. START BEING HEARD.
The Model HK4 is engineered specifically for drivers who demand maximum sonic impact and a sharp, classic Chrome aesthetic. This system takes our best-selling platform to the next level by utilizing a quad-trumpet configuration to produce an even louder, richer, and more complex tone than standard setups. With four tuned trumpets, the HK4 ensures you have the undeniable presence of a much larger vehicle, making it the ultimate professional-grade upgrade to replace a weak factory chirp with a head-spinning blast.
PROFESSIONAL-GRADE PERFORMANCE
At the heart of the system is a high-efficiency 130 PSI air compressor paired with a 1-gallon air tank. This rugged, oil-less system is designed for durability and "set it and forget it" reliability. Featuring integrated thermal protection and a complete wiring and installation kit, the HK4 offers a dependable solution for drivers who require consistent, high-pressure performance on demand. Whether you are navigating dense traffic or open highways, this system provides the air capacity needed to power through any situation.
BIG SOUND – SMALL FOOTPRINT
Installation is simple thanks to the kit’s clever, low-profile design. Despite featuring four distinct chrome trumpets, the compact footprint of the chrome-plated metal horns allows for a seamless fit in tight locations—such as behind the grille or tucked neatly inside the engine bay—where traditional train horns simply won't fit. By choosing the HK4, you are joining thousands of drivers who trust Kleinn Automotive Accessories for superior quality and "get out of the way" authority. Don’t settle for a vulnerable factory horn when you can have the quad-trumpet power of the Universal ProBlaster™ HK4.
