Hi All

How hard is it to replace I30 horn with something better?  I had the need to use the horn the other day and was surprise at how tiny that sound.

Has anyone upgrade their horn?

I agree. Mine sounds terribly puny. I might be interested in changing it out. I don't expect it will be very difficult: just locate it and reconnect the 12V line to a new horn.

Like most modern cars the Horn sounds more like a roadrunner "meep meep" so much so that people don't even acknowledge you

The i40 has a much better horn, perhaps give one a beep and see if it meets your needs.

I would think they would be cheap at the wreckers.

You’ll probably find that horn will sound similar to what you already have it’s definitely not a Klaxon trumpet horn though

Hunt around for an old 60 's Ford or Holden one.

Just meant to show how cheap an option you can get without going to the wreckers. Here's a search showing a range of them:
