Complete onboard air system

It makes its own air

No tank to refill at a shop, no scrambling for a compressor. The pre-assembled 120 PSI air source rides with you and builds its own pressure on demand, so the horn is always ready to blast.

The onboard compressor and tank build to 120 PSI on their own, then top themselves back up after every blast.

Pressure on tap

The tank fills fast and recovers even faster, so you are never waiting between honks.

The hard work is done

This kit ships pre-wired and plumbed. The high-flow air valve is pre-attached and the 120 PSI air source unit is pre-assembled, so you are bolting in a complete system, not piecing one together.

  • Pre-attached 1/4" high-flow electric air valve, ready to fire.
  • Pre-assembled 120 PSI compressor and tank combo, no air plumbing to build.
  • Everything in the box: wiring, fittings, mounting hardware, instructions and phone support.

Choose your air system

Same stealth-black 2-chime horns. The difference is the air source and how long you can lean on the horn.

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 blast, 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

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

This product can expose you to chemicals including lead, which is known to the State of California to cause cancer and birth defects or other reproductive harm. For more information, go to www.P65Warnings.ca.gov.

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.

Warranty

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