Stock Horn vs. Denso vs. BOSCH H3F vs. PIAA Oto Style

A comparison of car horn; stock horn, Denso Power Tone, Bosch H3F, and the new comer PIAA Oto Style (2019).

The test done in earlier June 2019. In this video you can see I use Denso and it was installed on my car since 2012 & it's still work and sound good! That's why it looks dirty.

Relay harness is NOT needed for these horn. Just make sure if your connector only one, then make custom cable just like I did or you can use relay harness for better sound and look.

Distance between dB meter to car is 5 meters.
