Fiamm Ultimate Blast 24v 

Fiamm compact air horn.
The Ultimate Blast is especially developped as an air horn that can fit in tight spaces under the bonnet. The Fiamm ultimate blast is a double toned air horn and compressor in one.
As cars become more compact and the space under the bonnet is used more efficient by manufacturers, it becomes harder to fit an extra pair of airhorns.
Because of it's compact design it is easier to find a place for it.

This Ultimate blast air horn is also availlable in 24v
