It's a capacitor.  It slows the rise of the high voltage, storing
charge.  When the spark finally starts, the charge stored in the
capacitor is dumped rapidly resulting in a briefer, hotter spark.
It will look bluer to the eye.  Nology wires do the same, but the
capacitor is formed betweem the braid and the wire core.

A similar effect is gained using a capacitive discharge ignition.
You get a short hot spark.  This technology predates our cars
by many years.  So, you might ask why do we have a more conventional
inductive ignition system.  It's to do with how long the spark
lasts.  On a turbo motor, a short spark may well get blown out!
The longer duration has a chance of relighting the mixture if
this happens.

So, if your coil checks out (resistance checks), your wires, cap and rotor
check out and you have new plugs, I doubt that you would see any benefit.

BTW, the examples on the web page seem to be of vehicles that were
showing symptoms of poor tune to start with.  One wonders what
a fresh set of plugs would have done for them.

W7DTCs are non-resistor.  Resistor types have resistance between the
center electrode and where the wire attaches.

Don't know.
