Probably less than 5K on them, with cool sox and wrapped headers. The silicone insulator turned brown and brittle, they pulled apart easy, even one of the boots split in half removing them. A couple left the connector on the spark plug, was wondering why I was idling rough. Only 2 wires made it after removing them.
The last two still ohm tested under 40 ohms resistance, but I went back to my old stockers, good thing I never threw them out.

The only wires that I have seen work for a while were Accel. But for the long-long haul, OE work the best - ACDelco, Motorcraft, Mopar.

I have had great experiences with my Thundervolt wires that are nearly a half inch thick! they have held up to heat on a few different cars that I have had them on....
