The latest and greatest on getting rid of the anemic factory ML horn is an air horn produced by the Italian company STEBEL. This is a one-piece unit that is a simple two-wire hookup using the factory leads.

This horn is called the NAUTILUS and it is LOUD!!! Virtually no lag time that is usually associated with electric air horns that have the compressor hooked to the horns via a length of tubing. The Stebel website will give you an idea of their sound/pitch, but the sound clip doesn't do them justice.....

I found them online for about $40.00 shipped and they are simply amazing!

Next time someone cuts you off or wanders into your lane while on their cell phone, a quick dose of this baby will get their attention.....
