Ignition wire disintegrated. Why?

I went to town to run a couple of errands and when I tried to start my car to come back home, it tried to crank but wouldn't turn over, I popped the hood and saw this.



I stuck the wire back on and drove home, but I'd like to know why this happened?

This is not an old wire, I replaced most of the ignition components about a month ago due to misfiring.

The weather has been wicked hot here lately upper mid to upper 90's some triple digits, could that be a contributing factor?

Faulty wire would be my guess, maybe too much resistance in the wire may have caused overheating and that would make the rubber degrade quickly.

Poor quality part? Make sure the new part has a tight connection to the coil post. Tighten if necessary.

Hopefully one of the local stores will sell me the single wire, I'm going to put the old wire back on for now.

They (the wires) were a budget set through Rock Auto, hopefully it was the only bad wire.

That would be an arc burn, the wire must have had a defect, it's like striking an arc with a welder, the wider the gap the more the wire burns.
