Fiamm Air Horns

I love these horns, here is a DIY.

First off you will need to remove the plastic panels above the radiator exposing the stock horns. The panels are held with clips and pop out.

Next remove the stock horns, the new trumpets fit best facing the passenger headlight.

To mount the new trumpets you will need longer mounting screws and several washers, the bell on the new trumpet hits the stock bracket causing the trumpet to rotate as you tighten the bolt resulting in an insecure mount. By using a longer bolt and washers you lower the trumpet on the bracket and the bell no longer hits it allowing for a very tight solid mount, I used a bolt about double the length of the supplied bolt. Take it to the hardware store to make sure you get the right size threads and diameter, you might buy a few lengths and return the unused ones, cheap enough to keep in the tool box.

I mounted the compressor in the passenger fender well using a shelf bracket, make sure you use lock washers for this. See pics.

I routed the air hose thrugh an opening in the headlight region, just find a hole, you don't want to go over the bulkhead, may compress the hose and looks unprofessional.

Wiring is easy, save some labor and try this first, I think you only need to run one wire to the compressor since it is an electrical signal and the compressor will send air to both trumpets. I thought of that after I did my wiring. I spliced the two horn wires (again I don't think that was necessary) and ran the stock fitting to + terminal on the compressor and ran a ground wire from the - to the ground nut near the compressor at the fender.

I don't like the horn chirp when locking my doors , the chirp does not signal the compressor hard enough to blow the trumpets, you can hear the compressor click but it is wasteful if the horn doesn't chirp and adds wear to the compressor so I turned that feature to the off position on the EVIC

Twin trumpets, Fiamm is the same supplier to Ferrari, made in Italy not China, $24.00 shipped from I think the regular price is $32. They have that great Euro high/low piercing blast like the Italian cars, not the alternating hi/lo of the Euro police cars.
I added this to my original description "save some labor and try this first,I think you only need to run one wire to the compressor since it is an electrical signal and the compressor will send air to both trumpets. I thought of that after I did my wiring. I spliced the two horn wires (again I don't think that was necessary)"
"That sounds really wizard"- Herman Munster. How do I make a sound file it is well worth posting.
I think I can do that, I have a digital 8 that I can put on the computer, then could I upload in the "manage attachments" section. will this work for video?
Sounds almost as good as my horns NR, I have to go by my office tomorrow and get my burner to load up, once I get the clip on the HD, I'll PM you for your email and get this show on the road. I plan to do an in car, front grille, and end of driveway clip, as well as the installed product, I don't imagine more than 45 seconds, any limits on length? Thanks
THe only service is a drop or two of oil in the compressor, I have had it approx. 1 year and it's perfect. Keep in mind I blow it 99% of the time for demonstration. The dead space in the tube is a great thought, kinda like having to blow the column of water out of a snorkle (my snorkle has a valve to keep it totally dry under water, from Herrington catalog). Back on point, thie only problem I have has nothing to do with the trumpet, it's the poor, defective horn button. Yes, I did use all existing relays etc, it is a simple plug and play and I used my own wire.
Glad to hear ,no pun intended, things went well jaydee, I love these things. Now if only somebody can figure out how to get a reliable horn button in the steering wheel.

Still no luck on sound NR, unable to compress the clip, If you have an office or PO box (can never be too careful giving home addresses over the net) I can mail you a DVD if people are interested in hearing it.
I'll get some trumpet pics, I mailed a DVD to NR who will get it hosted somewhere for a look and listen.
Oh come on, JC Whitney has them with Dixie, hat would be real slick in NY.
Glad you got some Pics posted, I have been in Cleveland (suprisingly nice downtown) and hope to get some more pics posted tomorrow.
Trumpets here, I used the stock location, wrapped the hose around the horn to keep it off the hot radiator unit below.

Yes, I got extra hose from Lowes I think.
Thanks NR for all your work, these horns are a huge improvement over stock, too bad we can't fix that sorry rubber horn pad.
My dad had one of those horns on his 77 Econoline van, got it fron JC Whitney for $9.95, you could hear him two blocks away.
