Why do stock GM (black) plug wires ohm out LOWER than GM red high performance ones? And what does it mean...?
Stock GM black ones ohm out @ roughly 345 ohms
GM red high performance ones ohm out @ roughly 375 ohms
I thought lower resistance was better....?
Anyone>>??

Maybe try testing them with a functional tester, or with your ohm range set correctly? Most "performance" plug wires will test at 40-50 ohms...per foot.
Chances are they tested at 34.5 and 37.5, which is really not enough to make any kind of difference. There can be a 10 ohm(or more) variance between one foot lengths of the same kind of plug wire, so 3 ohms difference in half a foot is pretty good.
Just goes to show that the OEM plugwires are just as good as most of the aftermarket sets.
