SE-R guys like them , or at least on their modded SE-R they made an improvement.
But, I'm looking through some newsgroups for info on them and lots of people are claiming snake oil. There are, of course, people that swear by them, but I seem to be seeing many more that say they're junk. Couple other websites (one for a probe, another for some FWD V6 GM) I found said they're junk. I can't remember seeing anything on here about Nology..
I'd say stick with the tried and true -- Magnecor, or those Ford Motorsport wires that Bill Jenkins was selling, or even Jacob's.
edit
Just go to
http://groups.google.com and search for nology plug wires and see what you come up with. You'll get a ton of hits.
