Hear these horns now!


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" valve already plumbed make installation even easier. 

Our HornAir 127H Air Source Unit and our Super Echo air horn make the perfect pair as our HornAir 127H Air Source Unit 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 air horn kit’s 1.5-gallon 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! 

As with all HornBlasters kits, our Super Echo 127H air horn kit comes complete with all required components and detailed instructions.

(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...)

**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 model kits. **

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.


Too much fun!

I got this kit as my first air horn to go into my 2018 Ford Explorer. I had a local installer put it in for me, took a few hours. The first time I hit the horn it was instant permagrin! I have a new superpower on the road! Love this thing.


Super Echo is right!

This horn really blew me away...HAHA, I was easily able to install this kit on my 06 Dodge ram 1500 in about 2 hours. The kit came complete with everything I needed to install the kit. Great job Hornblasters this kit is awesome and at the price, you can't go wrong.
