Description

The HornBlaster Spocker 3-Liter Air Horn Kit is the perfect entry-level solution for anyone looking to add serious sound without taking up serious space. Designed with beginners and budget-conscious buyers in mind, this compact kit delivers an aggressive, high-frequency blast that cuts through traffic and demands attention. Featuring a dual-chime chrome air horn, the Spocker proves that performance isn’t about size—it’s about power and tone.

Paired with a compact 3-liter air system, this kit is ideal for vehicles where installation space is limited. Operating at 110 PSI, it delivers up to 5 seconds of continuous honk time, giving you plenty of punch when you need it most. Even better, the system quickly recharges in just 35 seconds, so you’re always ready to sound off again without long wait times.

The sleek chrome finish not only enhances durability but also adds a clean, eye-catching look under the hood or wherever it’s mounted. Designed for convenience, the kit includes a pre-installed high-flow valve and a fully pre-assembled air source unit, making installation straightforward and hassle-free.

Whether used on its own or paired with a larger HornBlaster setup, the Spocker 3-Liter Kit is a versatile, compact, and powerful addition to any vehicle.

Important Notes:

  • Tank-mounted compressors are not fully sealed and must be installed upright in a protected, enclosed area away from moisture, dirt, and debris. Improper installation will void the warranty.
  • Do not detach the compressor from the tank. Doing so will void the warranty. If you need a remote-mounted compressor setup, consider HornBlaster 232 models or higher.
