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?
