You have a FI engine which runs much hotter than a normally aspirated engine. You have located the horns just above the exhaust manifold where the temperature is maximum. It will not only affect the wires but also the plastics in the Horn itself. Better to relocate it to another location away from the exhaust manifold.

Dude, that 800 is not turbo charged. What are you on about?

Hi Friends,

I would need a small clarification here.
I recently changed the stock horns on my Santro Xing to Bosch Symphony ones (The Skoda sounding set)
The current rating of the new horn is 5A and I have no clue regarding that of the stock ones. The new horns were installed at a reputed car accessories shop in my city, in plug 'n play (i.e., without any additional relay), just replacing the old ones with the new ones.
My concern is that in this thread I see relays being strictly recommended for all installations.
I had asked the guy who installed the horn if I would need a relay, for which he said it was not at all required.
Can anyone help me out here as to whether I should be installing an additional relay for the safety of the electricals?

While swapping Stock horn with Stebel Air Horn in i10, even though I had purchased seperate Horn Relay (the relay that comes in the kit won't suit) they never used any additional relay as the stock wiring has got the Relay

As per my opinion it isnt required as both are likely to draw similar current. All modern cars come with horn relays AFAIK.

It should depend on the current rating of your existing horn and the Stebel.

Hey Ankit, good to see that you are helping everyone so much. I owe it to you for my Nautilus too because I couldnt find it anywhere in Delhi and ultimately I got it from Suman Sir (this one was sourced by you). I still havnt used mine and what is stopping me is that once I get used to it will I be able to source a replacement when it will die as all air horns have very limited life.

My NHC is fitted with Roots VibroMax Horns. Thinking of upgrading to higher AH battery when the stock battery dies. Which one will retro fit in NHC, without much change. If anybody has done... input please

Retrofit what? Battery / horns?

You don't need Turbo Charging for the engine to run hotter. Fuel Injected Engines (with catalytic Converters) normally works at slightly higher temperatures for optimum efficiency, so the exhaust temperature will be much higher than a normally aspirated engine and the subject horns are fixed next to the Exhaust Manifold.

Search the Internet if you need more info.

@WanderNomad

Thanks for the info man. My only concern is that similar horns (like Roots windtone super, WIndtone trio etc.) draws 4.0 A while this one (and also new Roots W-90) draws 5.0 A. The stock horns which I removed doesn't indicate the current either, so a bit confused.

Anyone has any info as to how we could find the current rating of the OEM horns? The vehicle in question is a Xing

Cant really comment but I dont think there should be a substantial differnce in wattage / current rating.

dude i think you are confusing Fuel Injection and Forced Induction.a forced induction car is compared to NA one while fuel injection is with carburettor one.Even a fuel injection one can be naturally aspirated.correct me if i am wrong.

Its Battery. Is it advisable ?

What I meant was Fuel Injection and Carburetted engines.
Thanks for pointing out the error. Just "slip of the tounge". Sorry about that.
