Nautilus Compact Twin-Tone air horn The perfect horn for our small roadsters, this compact, genuine Italian air horn has four great features: 1) It's very small and compact (4.5" x 4.5" x 3.25") 2) It's VERY loud! (139dB) 3) It's all one piece - no hoses to delay response time, fall off, or kink 4) With the Thompson Automotive supplied mounting bracket, hardware, and instructions installation is a snap. $41.95

Nautilus Compact Air Horn - Horn ONLY Same great Nautilus horn as above, but without our Miata/MX-5 specific mounting kit or instructions. No Miata specific mounting bracket No wiring pig-tails (extension wires to connect to factory connections - plug & play) No installation instructions, lock nut, washer of 20 amp fuse. But the horn is the same. And it's less expensive than the re-branded Nautilus horn marketed as the Wolo Bad Boy. $34.50

Many who have ordered our Nautilus air horn to be heard better, have also ordered our Brake light flasher to be seen better. Check it out on the Brake line page.
