At 8x the cost of the old plugs, plus well over $300 to replace all 8 boots... no thanks, I'll stick with the old ones. I cannot imagine a benefit that would justify spending an extra $469 the next time I change plugs, and $150 each time after that.
From what I have read on the Rotax forum (just a quick Google search), the old or new boots will fit either style of plug.
Edit: Oh, sorry. I see you can go 200 hours on the new plugs as long as you're not burning avgas, so only an extra $60-some-odd per hundred hours.
