Hey,

Iridium is definitely better than Bosch Super 4 but only makes sense if you have a modded car(more than exhaust and filter). For basic mods Bosch Super4 should suffice they are far cheaper for Carb cars. Also it is definitely recommended to change the plug wires to get the best out of the plugs as otherwise you are defeating the purpose.

Hey, nd how much for the wires ? I remember i changed the plugs in my palio about 3 months back but don't remember which ones I put. Ill go check them and see which ones do I have as of now .... So, u recomend the Bosch Super 4 as my engine is pretty stock and only free flow and air filter is modded ??

And whats the difference that I wud feel after changing the plugs ?

Cheers

Also you should replace your plug wires from OE to better quality ones to handle the extra voltage. I think you have had a lot of bad experiences with performance products. First the K&N conical filter and then the plugs.

the Beru plugs were bad ...but i did not any bigg improvement inthe iridium plugs over the OE plugs ...as you say maybe performance plug wires would have helped..the iridium plugs did not show better performance than the OE plugs ...so i have got back to OE ...



abt the filter ...yeah i did find change in performance with teh stock replacement filter ...not only my car ...but other cars were also affected by the conical filter ...like a wagon r and a 1.5 city...both of which are running on stock replacement filters now.

Dude "Detonation" is not correct word, Detonation means blowing your engine its the word which no engine tuner would like to hear about his engine correct word would be combustion.

Thanks gurus,
lot of info, But i am still wondering anyone used Super 4 spark plugs.

ON the other hand, I also read in the web (sorry dodnt remember the link) that 4 electrodes may disturb the dynamics in the combustion chamber and cause loss of perfomance. So irridium is better.
I don't know how much water does it hold. Please enlighten...

I have used Bosch Super 4 plugs but my experience with them may or may not be relevant to your case since it was used on a two stroke 125 cc engine.

I do not know if they are available in different heat ranges, but the one i picked up was the only type available in super 4 (and also +4). I hated these because they were VERY cold and caused misfiring and fuel wastage. The engine constantly 4-stroked and never revved right. This after setting the proper gap on all 4 electrodes (which by the way is a pain in the @$$)

Moral of the story is check heat range of the plug and see if it matches the plug recommended.

Hey,

I am using Bosch Super 4 in my Santro, Getz and Mercedes 500SEl. I have seen a marked improvement over the stock plug sin the Santro & Getz. cannot comment on the Merc as the car is never pushed and is driven at leisure. Iridium plugs are definitely better but are useful only for modded engines otherwise the cost does not justify them.

PS - I also use MSD 8.5mm plug wires in both the Hyundai's

I have seen these msd wires with N1,
What immediate difference will i able to notice with the change in just wires or does the ignition coil also need to be changed?
Any other brands besides MSD?

Beru!!! I guess you are talking about Uber power spark plugs!!! Uber manufactures performance stuff and trust me they are good. if you didnt get the desired result Im sure the heat rating was incorrect or the plug gaps were incorrect. There is another brand called Splitfire, checked them out a month back I guess...they claim 5bhp gain with mere plugs...huh!!! I was livid to see such a blatant claim on the product box ...they are ideal candidates for sueing...

Well, JFI "no mere pulg can give you more power", plugs only burn fuel whats supplied to them. Better quality plugs last long and dont lose their texture soon, thats their advantage. If you think your new plugs are giving you more power is just coz your old plugs werent firing right due to several factors...

Performance plugs have higher hear resistance and can work under extreme modded conditions which a normal plug might not.simple.

Hey Wolf,

There is a very popular brand called Beru which is used on a lot of European cars. Uber Power is a different brand altogether.

how can plugs for a mpfi zen work on the 1L santro and other cars ...thats what i was told ...still to test it i fitted them before going on my mangalore drive ....it only resulted in sluggish pick up...the car would knock above 100 kph in 5th gear ,poor FE.....and more time due to which i could not do the drive in a single day ...i had to stay in a hotel near ankola ...as i dont drive after 7 pm ....the only good thing was that ...as we were staying at ankola ..i woke up early in the morning and did another ankola road drive on the ghats before my parents woke up

Hello Viper,

I am planning to get these Super 4 plugs for my Santro Xing. Are these plugs common for all cars or is there any particular type for santro 1.1L. Can you tell me which one to ask for. Also as recommended, I shall change the plug wires also.

Thanks
Prem

[PAVAN KADAM]

Have been using one in my M-800 and VW-Beetle, since 3 yrs, very reliable, have to change once in 40000 kms. Great Sparks

[viper]

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)
