I rest my case...
There is more to it than that if you look a little closer.
8mm wires will fit in the stock wire separators. Bigger will not. That adds expense to the installation.
The molded end prevents rotation, offers a better grip and seals better than the slip over boots.
The spiral wound SS is more durable than the softer nickel / copper.
Each has advantages. Why do you think they sell more than one wire set?
If you are really looking for an extreme performance wire and don't mind buying new separators, cut to the chase and go with the "409" 10.4 mm wire
. This is the bullet proof high heat / high power ignition wire set. Actually recommended for use with MSD and electronic ignition systems. Be prepared. It is like running ignition hoses.
Any wires are better than stock. Taylor wires are a good choice. Hard to go wrong there.
BTW. This topic was split as off topic from another thread. All this is a repeat from a thread over three years ago: Plug wires
We are doomed to repeat everything it seems.
