There are different versions of the coils trying to make them more reliable, but in the US, all the coils are interchangeable.

Physically interchangeable, but it should be noted that Mazda parts docs specify that nothing earlier than a Rev B coil should be used on an S2. I can't speak on why, or if failure will ensue ... or if you can even find a 'rev a' spec these days, but just wanted to throw that out there.

Thanks - I was just driving the car and whoa - loss of power suddenly happened. Hoping it is just the coils...
But the coils in this picture above do no look like what i think my old ones looked like!

I got the oem coils online. They were actually listed as rev B, but when I looked in the box they were rev C. They seem to be holding up well after ~14 months with 12k street miles plus around 15 track days. I would expect any that you order now to be rev C and these should hold up pretty well.
My original coils were rev B ~3yrs old with 30k on them. No noticeable issues driving, but the car did not dyno well so I decided to replace. A subsequent dyno was much better and I suspect, but don't know for sure it was the coils that made the difference.
BHR would be the aftermarket choice, but I decided to go oem and simply replace more often for the same cost. My plan is to dyno the car again when the current coils are ~2yrs old to assess their condition unless I notice any issue before then.
