MCS spark plug thread size

What size thread is the MCS spark plug?? 12mm or 14mm? I am currently looking at getting some BRISK plugs in Australia, and the company is recommending BR12YS, and everyone here is talking about BR12S! He says the diff is the YS is 12mm and the S is 14mm...

So some clarification is needed before i shell out!
