Bosch Spark Plugs Super4

[quote=viper;382393]Hi Prem,

Would recommend you go in for the OWS Iridium Plugs instead alongwith the plug wires instead of the SUper 4. There are different plugs for different cars so make sure that you buy the right ones for your car.(I think the same type of plugs are used by a manufacturer across their variants)

Viper

Thanx Viper, is OWS different from NGK Iridium plugs? How much do you think Iridium plugs and the wires would cost. Do you think it would be cheaper in the U.S, if so I can try and get it from there.

Thank you
Prem

Just reiterating what others already have Prem... Plugs and wires alone wouldnot give you any noticeble performance gains over your stock ones in good condition.

I am using NGK iridiums with a heat rating of 7E which is a cold plug meaning they do a better job of keeping your bore temp relatively cooler.

The 4 electrode plugs normally give you a marginal gain...coz 3 extra electrodes occupy more space in your combustion chamber increasing the compression one wee bit however do not forget that 3 additional electrodes means 3 more obstructive protrusions to disturb the flow of gases in the right direction. Now its for you to evaluate where you are willing to sacrifice!!!

Are NGK Platinum plugs available in Bombay? If yes do they give a noticable difference?
How much and where to buy from?
Any better recommendations?

EDIT: Car is a 2003 GTX

i ve been told by a expert tht i cant go for an iridium for my fiat adventure 1.6. he also told tht i should go for a platinum plug. i wanted to upgrade so as to ve some increase in pick up between the gears.

i want to know whether the warranty will cease if i fit any such spark plug.

From what i understand the car company's can even void your warranty when you change into alloy wheels............so making changes with different parts in the engine will be a good excsue for them to void your warranty. So maybe you should just change them and be quiet.

And make sure they dont change your plugs in one of the services and throw your hi-performance plugs away

Yes it could happen............well almost anyways.......

Is this Super 4 is what is termed as a Multi Electrode Plug, Since I remember BOSCH Website had a 4 Point Plug specifically made for CNG vehicles(This was a long time back), It claimed better spark and power..! Is it the same...! That was when I had checked the website in 2003, now no mention..!

presently am using MGP plugs

one of my friends also complained about the 4 electrode plugs...
he said his engine felt diff and got bad mileage...
maybe wrong spec plugs.. but I think he is pretty technically sound to not make that mistake.
also on some forums the mods/admin have advised against 4 electrode but haven't given any hardcode tech reasons...just that they "feel wrong"

Folks, I have been using the Bosh 4 point plugs in my Santro Xing for the past 2 years. I had picked them up from the Bosh dealer in Pune, they have different sets depending on your vehicle model.

Didn't notice any marked difference in performance after changing the plugs.

After reading chetanhanda's post above, I'm now apprehensive about the plugs, my vehicle mileage has dropped by 2kmpl for the past 1 and half year and now only gives around 11 in city compared to the earlier 13, during the servicing the company claims everything is ok.

Guess I'll try swapping my plugs for the standard version and see if there is a difference in the mileage. Shall update you all once I find out.
