Reading an article on grassroots motorsports web page came up with this:

Ignition Wires
Ignition wires are free in Solo's Stock class: the rules state they may be replaced with pieces of any origin. From the data we've collected, it's a worthwhile modification.
Replacing the brand-new stock wires on our BMW 318ti project car with a set from Magnecor gave us around two additional horsepower at the drive wheels, while our Neon got a three-horse bump when we replaced the stock wires with some hot ones. Installing a set of performance wires on our Honda CRX project car didn't unleash any more power, but the new horsepower curve was both smoother and no longer fell away at the top end.
In testing with a variety of cars at our Dyno Day events, we've found that nearly every vehicle benefited from having the stock wires replaced with quality aftermarket pieces from companies like Magnecor or Ignition Equipment. We found consistent power jumps in the two- to three-percent range; that's pretty significant. Plus, performance spark plug wires don't cost that much. Figure $50 to $150 depending on the application.

now ive always told and been told that plugwires are useless unless your bigtime fi with a hella ignition system/plugs/etc. but what about that? grassroots motorsports is someone id consider a reputable source so i mean it seems to differ from everything ive thought and been told. they seem to claim it dyno proven as well..... discuss.
