Hi Guys,
Wanted to know your take on the NGK Iridium IX Spark Plug for the R15. Does it really boost your bike's performance and if the answer's yes then is the performance good enough to match its price of Rs 550/-?

Sagar, the Denso brand plugs that come with our bike suck. Mine burnt off even before 3k kms, the only reason being due to the extra heat generated by higher octane Power Fuel. ANd my second plug(denso again) is at the end of its life too...I can feel my bike skipping a few combustion cycles when the throttle is opened.(less than 1k kms after the change). Those plugs are just not able to take that high temperature at the RPMs that R15 operates at.

So, my guess is that the NGK Iridium ones should be value for money. They'll atleast be more reliable and efficient than the stock Denso ones!

hey hi bro.....i told you few days back that i had the same prob right, i got it solved by the SS guys in chennai, they just rolled a insulation tape to the adapter....and the prob is gone or it was very less for me to realize.Now there is no spark on the spark plug,better check it with your SS guys before you replace it.

@148kmph guy----u can use CR8eix or cr9eix . Both ll fit.Whether worth or not u decide.

My opinion Iv used them for so many kms, its good. not bad.

-- How faster do u wanna go with those plugs man

LED for the ones who were asking about it.

continuing OT :- IMO FZ is turning out to be quite a poser bike. With ease of changing colours etc. naaat baad. Luckily no FZ owners on this thread to pounce on me .

. Kindly do not reply to this as I said it is IMO.

@Archi,

You did receive a call from SS, in my case I think after looking at the spreadsheet they wld have thought to play safe and not to call me up as they have already faced the sweet music volleyed to them regarding my first R15. And a problem of this magnitude with 2nd R15 they surely know I will make them sit on a donkey with face colored black and marched at the trumpets sound towards CMH road.

After looking at the spreadsheet they should have at least contacted everyone. I very well remember how aggressive they were about selling the bile when I was out of town, they used to call me twice a day almost everyday, what happened now??? I think many of us did not receive any call from them, anyways I will try getting it fixed from Panache on my 3rd Servicing on 30th Dec.

Yamaha, the wood is lovely dark and deep and you better continue to sleep!!!

**archibaby** · 12-20-2008, 12:37 PM

Just gave my bike for tappet valve adjustment. I'll be at panache from 2 onwards to personally oversee the work.

@amit + anyone else : join me if you want to. They can take more pics of the rust etc. I'll most likely be shifting to BW for the next service.

@ digislayer- Thanks for your input man. Appreciate your help.

@ santoosh- Thanks for your feedback. I did some research on the both the plugs that you recommended and the website said that the plugs improve your throttle response and smoothen your ride. As you have been using them for a while, did you notice these changes? As for your speed remark man, I am really happy with what my bike has achieved so far

I was just curious if these plugs can help better its initial response.

Dude, you should never a expect a huge difference in the power output of a stock engine just because of changing to a better spark plug. The advantages you can expect are:
1)Better performance at higher RPMs.
2)Longer life of the plug when used at higher RPMs.
3)Longer life of the plug when used at extreme load conditions.
4)More precise engine firing,especially at high throttle conditions.This might in turn lead to better maintenance of the engine.
5)A slightly better fuel efficiency(maybe too less to be noticed).
6)Cleaner emmissions.

Hope this clears your doubts

And yes, I do recommend upgrading to better spark plugs on the R15. That's because it has a higher compression than other similar bikes of our country, it runs at a LOT higher RPM than other similar bikes of our country. I can explain you how it works if you want me to, but i'm not sure if it'd be OT :P

i ride at pretty high revs generally shift only at 8500+ so will a spark plug change be advisable..becoz im worried about teh longevity of teh engine by placing it under stress...at teh same time dont want to play safe as teh reason for getting teh bike will be lost if i have to shift at low revs..

@digislayer where can i get better spark plugs in hyd?

Dude, I'm not quite sure about the magnitude of longevity of engine life that a better spark plug adds. But I guess the R15's Diasil cylinder material should be good enough to handle revs of 10k RPM. The R1 is made of the same cylinder material and works at 14k RPM, at a much higher compression. So I'm guessing our R15 cylinders should last longer than an R1's cylinder even at stressed conditions

Regarding the advantages, I slightly edited my previous post..go through it again. And I guess you get performance spark plugs at almost any good automobile shop. Try koti,minister's road, etc

**harshaguduru** · 12-21-2008, 04:13 AM

@digislayer... thanx a ton for the info..since they arent covered under warranty like the rest of teh bike,,i will be changing them this week..
