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
