does anyone know of a site where you can find the specs for these, have them on a duacti that runs like a bag of **** . Have put a multi meter on them but dont know if they are right or not and cant find a damn thing about them, seems like freedom of information doesnt apply to these

You mean Denso copper cored plugs? Found this:

I NEVER use anything but NGK Iridium`s these days, can`t fault them.
You might find this site useful too:

I think he means Coil On Plug

Yes coil on plug is correct. The number on mine is

129700-4201 j0420

The 129700 seems to be on lots of them so I would think the values specific to this COP is derived from the rest of the numbers but blow me if I can find any info at all on them
