Anyone try these Accel 5mm plug wires?

How do their internals compare to other plug wires? Smaller diameter means more resistance unless their internals are far better than the others.

The MSD plug wires have the least resistance.

MOst aftermarket wires have similar cores, and the difference in thickness is just the extra silicone for heat resistance, and so noobies can say they picked up a couple hp by switching from 8mm to 11mm

Maybe that extra HP comes from the power they were losing from one non-firing cylinder whose skinny plug wire had burned through and was shorting out against a header or valve cover...?

I don't think anyone ever really lists the diameter of the plug wire CORE, as opposed to the surrounding insulation. I figure it'd work the same as a battery cable - bigger cable will have less Ohms per foot, right? (Hence the reason it's necessary to run 0/1 gauge cable when relocating the battery to the trunk.) You could have 20mm insulated wires for all it mattered, but if they're no different or larger internally, running the same plain ol' copper wire that everyone else does, then the difference means nothing.

If I weren't so worried about heat and short-out issues, I'd be looking into a set of skinny plug wires, too. Being that everything out here tends to dry up and crack and stuff in such a short time, though, I think I'll stick with my cheap-o 8mm Accel Spiral Cores. (They were cheaper than regular OEM-fit aftermarket wires, and they're a pretty blue color ... which adds, what, 10hp? )

My bro inlaw runs msd wires. he is happy with em. i have ford racing wires and they seem to work very well. i will probably go with msd wires next time.
