Hi All,

I apologise if this is old news, but I'd never come across them before, so thought I'd post them for anyone interested.  It's a coil that mounts on each spark plug and cleans up the left hand side of the engine nicely IMO.

Anyway, here they are if interested!

Oh, and yes, they're not cheap of course...

Cheers.

Clever design and looks pretty cool.  I'd be a little worried about the wiring getting cooked from sitting between the fins though.
