To my mind, fine-wire plugs have to run pretty hot to keep from fouling, and
that means they have small, hot, pointy parts to them when running. I opted not to go
for them on my 180hp Lycoming I run mogas in for fear of preignition. If you run a
low-compression engine, it's probably not any cause for concern.

Just food for though, though...
