(Note: Tank-mounted air compressors are not fully sealed. For this reason, the manufacturer recommends the tank/compressor system be mounted in the upright position in an enclosed space away from moisture, dirt, debris, etc... Failure to mount this product as directed will void the warranty)

Detaching the compressor from the tank will void your warranty on this kit. If you need a solution where the compressor is detached, please look at our 232 and higher models.

Reviews

Before you buy

Do I need an air compressor or tank?
No. This is a complete onboard system. The 120 PSI air source unit (compressor and tank) is included and pre-assembled, so the kit makes its own air. You bolt it in and wire it up.
How many honks do I get per fill?
A full tank holds about 5 seconds of honk (4 to 5 on the Non-Weather Resistant system, 6 to 7 on the Weather Resistant). That is total air time, so spend it however you want: one long honk, or a whole string of quick honks. The tank then tops back up from 90 to 120 PSI in roughly 35 seconds.
What's the difference between the two air systems?
Both use the same stealth-black 2-chime horns. The Non-Weather Resistant system uses the AC-M3 3-liter compressor and tank combo. The Weather Resistant system uses the 127H 1.5-gallon unit with a weather-sealed compressor and a 6-foot snorkel kit, for longer honk time and real-world durability.
Will it fit my vehicle?
The kit is designed for 12V vehicles including trucks, SUVs, cars, RVs and boats. The compact air source makes it well suited to tighter installs.
How should I mount the air source?
Mount the tank and compressor in the upright position, in an enclosed space away from moisture, dirt and debris. These tank-mounted compressors are not fully sealed, so following the mounting guidance protects the system and your warranty.

Warranty, returns & mounting

Buy with confidence

Compressor & mounting rules

To keep your warranty:

  • Both kits: never detach the compressor from the tank. Need a detached-compressor setup? See our 232 and higher models.
  • 3-liter (Non-Weather Resistant) only: its tank-mounted compressor is not fully sealed, so mount it upright in an enclosed space, away from moisture, dirt and debris. The Weather Resistant (127H) unit is weather-sealed and is not subject to this mounting rule.
California Proposition 65 Warning

Hearing protection recommended

These air horns are extremely loud. Wear hearing protection when testing at close range, never honk directly next to a person or inside an enclosed space, know your local regulations, and use the horns responsibly.

The complete kit, horns and air system, is backed by a 2-year manufacturer's defect warranty.
