Rupse 12V 450mm White Zinc Tube Single Trumpet Long Pipe Plating Car Air Horn 150db Car Speaker

I give this air horn good marks. It is actually made of metal and produces a rich, low tone like you would expect for a "truck" air horn. Unfortunately it did not come with a relay but those are a few dollars at the auto parts store and the directions to wire a horn relay are with the part. Time will tell if it lasts but so far, I'm much happier with this than I was with the dual air horns of poor quality and high pitched sound.

sounds great everyone says it sounds like a tug boat lol mounting was easy i did need to go buy longer air hose you get like 14-16inches of hose i installed it on my 1997 jeep orvis under the hood with minor drilling

Loud!Youtube search "450mm air horn" for an example of toneYou will need to buy an inline fuse, a horn relay and a 30amp fuse.

Very loud, fun horn if yours sucks. Will take a small amount of wiring know-how.

exactly what i want
