Only downside there is if for whatever reason they turn out to be crap then you'll end up replacing them again anyway.
I've always stayed with the iridium NGK's because they're totally reliable and long lasting.
Can't imagine any improvement with any other brand to be honest and for the sake of pennies is it worth the risk?
More people are born because of alcohol than will ever die from it.
Thanks for the reply Darrsi,
I have used Bosch in cars and on the boat engines (V6 inboards) for many years and found they seem to last and perform just as well as the NGK's
The boat has proved to be the harshest enviroment, even there I have only ever changed plugs due to other faults like leaking exhaust manifolds (they are water cooled) leading to burnt exhaust valves and susequent damage. Thats another story, they can be bastards at times and had to do a couple of top end rebuids and thats a mare on GM V block in a restricted space.
So I have full faith in both brands. So it comes down to availabilty and price. I am in Guernsey and everything is a rip-off over here, the duty on them on an island like this I dont think warrents iridiums, I'd expect to get at least 5 years out of standard ones ... [oh, where's that skin-flint thread :lol ]
really it was a question of any experience and whether I have cross referenced right, If I had found the Denso's cheapest I would have gone for them as they are listed in the manual, and I welcome any coments on them for background knowledge, I'm sure I saw someone on here had Nippon Denso's in their bike
I've just bought some NGK CR9EK 4548 for my 05 FZ6 they cost £6.75 each with postage (free) not fitted them yet, by the time I do the bike will have done 39,000 miles on the original set, never missed a beat if you put cheaper ones in and replace them at the recomended mileage then you should be ok, but will you save any money?
