the guy on ebay that i bought the air horn from wants $20 for a replacement compressor, even though the entire air-horn kit with the compressor and relay is $29.99. Anyone know an online source that sells cheaper replacements?

 

What are ya putting the air horns on?? If your looking to have a sound the comes close to shattering glass have I got the horns for you. Almost any pre 12 volt battery system horn will do just fine. Mainly old american 40's and 50's cars, just make sure you have an inline circuit breaker and a momentary contact button/switch. It'll knock the paint right off your hood, at least damn close to it.

 

this is what i've got

and this is what they sound like

see sig for a pic of the horns on my truck.

 

I just bought a replacement compressor on ebay for $17 shipped.

 

you can get the whole air horn system at harbor freight on sale for like $12

 

I second that, cheap and effective

I used to have a set of Packard horns and I can't agree more. They were loud but not as loud as a set of Caterpillar airhorns with 175psi
