Difference in ohm rating on plug wires?

Seems like the focus on "resistance", blinds many of the fact there is inductance in the circuit too.

The secondary circuit of an ignition involves the ignition coil seconday winding that has inductance, redistance, and the series resistance and inductance of plug wires followed with the plug gap. The coil winding is typically the predominate factor. Prior to spark, current doe not flow, so the effect of resistance is nill. When spark happens, the plasma in the gap conducts, is has a low impedance, the gap voltage typically 50 to 100V. A portion of the stored energy in the coil primary is transfered. The spark duration, and current is related to the energy stored, and the circuit elements.

Viewing primary voltage, and current with a scope, is fairly simple. The information from that, when used with math and circuit values, answers much.

Viewing spark current, is a window into the combustion event, the current profile follows the flame burn, and even the texture of detonation. That takes a long duration spark method.

Typically enough spark is enough ... The initial trigger has high peak energy, the typical conduction that follows helps, but multi-strike is superior. Modern ignitions use multi-strike for cranking and lower RPMs, the little coils are designed for that... they are better than you think.
