You’re getting an air horn to stand out in a crowd, right? What better way than with an obnoxiously loud air horn with a tone, unlike anything you have heard before? With our Super Echo 127H air horn Kit, you are sure to get everyone’s attention with one of the most jarring tones you have heard from an airhorn and our budget-friendly, compact HornAir 127H air source unit. 

Sure, we have some horns that are louder, but we guarantee that there are few horns that can turn heads as fast as our Super Echo air horn can! This dual-chime metal horn’s unique tone comes from the large resonance chamber between the two bells, giving the potent mid-ranged tone an echo effect that will leave your jaw on the floor long after you blast it. Our Super Echo air horn comes with the required 1/4" air valve already plumbed make installation even easier. 

Our HornAir 127H air source unit and our Super Echo air horn make the perfect pair as the HornAir 127H is pre-plumbed and pre-wired, making the Super Echo 127H an air horn kit that is not only insanely loud but incredibly easy to install, making it a great beginner kit! Our Super Echo 127H's 1.5-gallon air tank provides enough air to blast your Super Echo air horn for 4-5 seconds straight and the tank-mounted Viair 275C air compressor will recharge the tank from 90-110 PSI in a blazing 35 seconds! 

  • All-inclusive air horn solution!
  • 120 PSI Air system
  • Unique pulsing sound
  • Max honk time: 3-4 seconds

(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. **

Louder then expected

This kit is super simple to install. I modified the wiring a bit I wired the compressor to a toggle switch and the horn itself to a horn button I got on Amazon. Definitely louder then what I expected. Was able to mount the horns up under my front bumper on the core support.

Trade out for louder horn

The kit I first received was not as loud as I had expected. The tone of first horn was great but it was not loud enough to make a texter in my lane drop the phone so I got with hornblasters and they sent me a 4 horn replacement called a bullet and it has the tone of a car horn but it is very loud. I just wish the tone was deeper than it is but guess this is not a perfect world. The customer service is great.. I will choose them in the future and the products are sturdy and well made. I am a 27 year pro auto tech disabled and a Reverend now and have to say the installation was a breez Rev. Tucker .

Super Echo is Super Awesome

These guys are the best! Again Alex, Tyler and the rest of the Team at Hornblasters...Thank you! This took my truck to this next level! The install took me just a couple hours and it turned out amazing. I love the fact the the horns are interchangeable so I am already looking for another horn just so i can swap them back and forth! I bought an electric horn for my Kawasaki Mule and have another one to mount this weekend for a guy. Great Products and Great Customer Service is an understatement. I promise you will not be disappointed with anything from Hornblasters!

Great horn kit for the money

I put these horns on my Tundra by myself, took me about 5 hours to get them in. I did have to call Hornblasters a couple times to get some help (my fault) but they were great to deal with. They are louder in person than I thought they would be, I am very happy with them.
