Fast forward a few years and $4 is now almost $50.

I’m glad I’m not the only one who also believes the horn is an issue. I knew the day I bought my Mazda 3 that I have to change it to something more substantial

[javidmirza]

Just replaced mine after waiting for warm weather to allow me to work on the car in the garage. I went around listening to different horns that different cars had and then nicked the info on the one I liked and bought that horn

I may be behind on the updates but what happened to the FA5? You’re actually one of the main you tubers I use to find parts for it and work on. Good video though mate!

People underestimate the importance of safety "mods" (upgrades)

And just like that Mark went right back to being gone LOL

Great video but I have a few questions, so with the harness I am be able to put up to 3 horns in the car ? And the plug and play thing is just like making the 2 horns work like one ? Lastly, do you need to do any welding to the cables or do anything with the fuse box ? I’m planning to do this soon so I need to make sure I know what I’m doing 😅

You don't need to add a relay... the original horn has its own relay already. You could just add a ground strap for each horn and make a split from the power wire to each new horn

I got my 3 used. Also has 1 horn but on the other side has a socket and nothing is connected in it. Is it for another horn ready wiring?

[VeeTravels-mmqi]

what do you do if the horns is still not working after the replacement, and the relays and fuses are working but there is still no horn sound?

2015 mazda 3 has the worst stock horn to ever exist

[michaelkeller]

sadly, i'm great in taking things appart, but the issue: no one is able to put these things together again. as the labour going into changing the horns will be around 200 to 300 bucks nowadays, i guess i'll just revert to screaming at the other cars that'd require honking (sure my vocal cords produce more soundpressure than the mazda3's horn)...
then again, with all the savety-requirements these cars need, i wonder who allowed mazda to use THESE ...i don't want to call them horns... on the mazda 3... (my cousin drives a mazda 6 - they got normal horns - why didn't mazda just use them?! )

[Joey-bjnz]

So Mark came back to get some free coilovers. Got them. Then left again? lol

[williamtucker]

Where can I order those horns and plug-and-play harness, please?

[shawncausten]

Did you buy a separate ground for the driver side horn. I don’t see any other ground in the wiring kit and I’m confused now

[nathoonathoo]

Do you watch Dustin williams still he has a vars kit on his r35 and do you still have canon camera with the rode mic still he have Nice cars

[daddydalyn]

Pretty sure this adds like 50 hp or sum

[coralyang]

Wonder where you get the heads up display? Thanks so much !

[nathoonathoo]

Do you watch Dustin williams still he have a lot of cars and he has a r35 gtr

You don't need a relay the car already has the stock horn relay which is plenty to handle the power just wire in the positive and negative. Why add all the extra complication and wires of adding a relay on top of another relay .
