The old wires had a resistance of over 6 Ohms?
The ignition wires should have had something over 20K Ohms of resistance which is purposely added to them to prevent them from generating electrical noise/static that can screw with the ECM and the radio. It's FAR cheaper to make ignition wiring with essentially 0 Ohms than to make it with the amount of resistance needed to prevent them from generating noise.
Due to the extremely low (micro-amperes) amount of current passing through the ignition wiring, the added resistance does not reduce the voltage provided to the spark plugs in an amount that is meaningful. Ohm's Law and all that.
So-called "Low Resistance" ignition wire sets play on people's misunderstanding that low resistance must be a good thing but it's not where ignition wiring is concerned. For ignition wiring, the low-resistance thing is strictly a misleading marketing ploy that sounds good to most non-electronic types. The voltage reaching the plugs via standard high-resistance ignition wiring is really not much different than is produced by low-resistance wiring. The difference, due to Ohm's Law again, is totally insignificant.
