Its hard to see from the picture but it appears that the plug and injector are in the opposite positions to where a 90 triple would be .
The indexing line is more like sector A on the 90 if you are looking at the plug end on .
Or as was said eariler between 1 and 3 oclock in relation to the injector .
As far as getting the right plugs from the dealer should you need them , why not remove the plugs marking which cylinder they are from and then match up plugs at the dealer . Surely all you are looking for is a plug where the thread starts at the same position in relation to the electrode .
