lots of failure modes in wire. (HV, HT) high voltage , high Tension.)
here is one more, insulation .
Insulation when old can act as a sponge,
and when the engine cools , or is a rainy or foggy night
the wires suck up moisture (junk or old wire)
this makes starting it harder and once started, it misfires, until hot and baked dry.
one more common failure of spark wire, endless for 100 years this problem.
if the wire as a water pipe and it leaked water, the owner would see that.
but seening electrons leak is kinda hard, yes you can see some (not all) leakage with eyes adjusted to the dark, and running engine in the dark.
newer better wires have better insulation that doesn't crack and break down at 200f engine heat or fail from vibration.
My guess is the better wires last twice as long, but cost twice as much.
whats best is a owners choice.
