I just received my FIAMM El Grande horns and they are nothing more than AM80S horns with a red cap and grille. Im so pissed about this because you can get these at NAPA or even Advance auto as they are made for various companies and re-labeled. Its only laughable, i clearly put too much thought into deciding which way to go, the AM80S or El Grande, which are "based on the proven AM80S design". Hilarious. I passed on the 80S because i thought the grandes were going to be special but the model# stamped on them is AM80S. To add insult to injury, when i took my intake off my 2010 F150 while i had the hood open i looked at the horns.....the AM80S is stamped right on them! Ive spent way too much time on this, i couldve just looked under the hood of what had a good horn to.start. i think someone on here went to a junkyard and got some off an old F150, which is my new recommendation. Dont waste time online if you can get them locally, unless you like the red caps and crimped on grilles. Im just laughing at myself at this point good luck dudes, and as always, this is a great forum.
