I've been saying that for the last 6 months,first having posted it at RAT back then. But i guess not many read my posts. But yep, thats true and it's also why there's always been confusion about which iridium is the right one. If you look up the correct iridium for our bikes the answer they give is the 9 which is wrong. But if you cross ref the iridium from our CORRECT stock plug then you get the proper answer. I even emailed them about this months ago but i guess they could care less.
