I kept going through compressors on these Hella-brand air horn kits, probably went through 3 or 4 in total. Picked up the newest version from Griot's Garage and am hoping for the best - at least they offer a product guarantee.

The Hella horn kit needed a custom bracket that I attached to the factory horn bracket, and looked like chit. Very happy that this new version is much simpler and attaches nicely to the factory horn location.
