You need 3 sparks. In my modest opinion you do not need iridium sparks. They take more time to work 100% compared with the OEM ones. The difference is that they last longer. You will spend more money and you will get no benefit.Hi,
my F3 675 has 12000km and so I want to replace the sparks with iridium sparks.
How sparks are necessary? Are NGK iridium sparks good for F3 675?
You are absolutely right. My garage only changes the sparks when they are out of specification not by mileage.Replacing spark plugs......
Why do plugs last 80,000mi in cars and 7,500mi in MVs?
Because they want to sell you PARTS at inflated prices and charge you stupid labor for screwing you on the price
Basically the NGK CR-9EIX spark plug is the standard of the motorcycle industry
On eBay 4 are ~$26 and change +~$2.80 shipping
Can't get them in your Country? Buy them on USA eBay and have them sent to me, I'll ship them to you
for actual postage cost......Duty? They are gifts
I know this isn't a like-for-like comparison, but only last week I had NGK Iridiums installed in my 2004 Fireblade. The difference in performance and smoothness was astounding, although I cannot say how much was due to the plugs and how much was due to the ECU remap at the same time.
Granted they are expensive, but a small cost multiplied by 3 is to my m,ind a rewarding investment.[/QUO
Believe me it was because of the remap. You can search in the internet and check that I am right. And if your mechanic is a good one will tell you the same. It makes no sense to use iridium. Only in cruise bikes that you do a lot of miles. Not for Racing bikes.
For me, that's the key. It's not a matter of being big-headed or pretentious; it's because we want to feel assured that we have the best quality product for the purpose. Fortunately, that doesn't always equate to dearest price!I do sleep better at night knowing I have the best . . .
That is a good justification. I completely agreed with you. Some options are only to made us feel comfortable and confidentFor me, that's the key.
