Today I installed a Steibel air horn to replace the whimpy stock horn. Bought it on EBay.

Turns out the horn has a bracket on it that holds the factory nut and allows you to get the nut close to the rubber isolater, the slip on the horn and rotate the horn until it's really tight.

I'm thinking I may put some locktite on it just to be safe.

It doesn't look bad to me. Hardly noticeable. Here is a before and after shot.





It also came with a relay, per the service manual there is no horn relay in my factory wiring so I will install the relay later.

Overall about a 3 minute install except for the relay.

I will say, it's very loud, easily twice as loud as the factory horns. Between this and my loud pipes I hope to get people's attention when I want to.

 

you SHOULD use a relay.

the compressor for the air horn draws more current than the stock horn.

while you may not have trouble next week, over time the contacts in the horn switch are likely to arc and pit, leading to failure.

the relay takes very little time to install, pull the tank.

my first air horn ( howie) worked for a short while then turned into a sick cow

currently running the HD- which I bought from a forum member stripping a wrecked bike- better than average fit and finish, exacting instructions- retail cost is stoopid.

I run a 6 volt horn on my FXRP, loud as heck...don't lay on it, flames'll come out!

Installed nicely under oil tank. 139 db LOUD!!!! Kept the stock horn for in town.

 

what was the cost? how were the directions?

 

Watch the water intake..I went through two air horns because water got into them. They are loud as hell when their working properly though....

 

Looks good and sounds sweet....
What was the cost of it? Much better than the stock unit for sure....

 

You will notice a difference too on performance. Easy to do.

 

I was thinking of getting one of these. I'm not good with wires, etc. so was concerned about how to wire the relay. How hard is it to do?

 

Is it louder than the "loud" Harley horn, part number 69060-90G?

 

I just honked it in the garage, it made my ears hurt. It's really loud, louder than my Cadillac 4 tone horn I installed on my car.

It was $34 on Ebay, it's nice that it was designed to basically bolt right on.

Relays are easy to hook up, they all have the same hookups and terminal numbers which you can get from the internet. Terminal 85 to ground, 30 to the battery (install a fuse), 86 to the factory horn positive, 87 to the new horn.

Here's a great link I just found.

I may run a relay later...frankly I have never used the horn before on my bike and don't really plan to now. Although, it is fun to blow that loud horn so perhaps I will do it more often now and if I do, then I'l run the relay.
