I was just checking out some sets of plug cables with a digital multi-meter and got some different readings. The Taylor spiral core had about .9 kOhm, but the Mallory suppression cables with a fibrous type core read about 23 kOhm. I'm sure it's a different ball game when they're zapped with 50,000 volts, but what is acceptable in choosing the best cables from a box full of new and used? I run a HEI with a good module and coil.

less resistance is better. If you have a mixed set, Ohm every wire, and get the least amount of resistance you can for each cylinder.

The trade off is noise suppression. Passenger car wires are high resistance to iliminate noise in your radio (and "noise" picked up on low current sensor wires).

Good racing wires are normally low resistance (1k ohm per foot or so) so they can deliver more energy to the plug.

Most racing wire manufacturers will provide the (resistance) specs on thier products.
