Difference in ohm rating on plug wires?

Thanks guys was just curious. I have the taylor spiro pro 8mm wires and they are 350 ohms/ft. Was thinking of swapping a set of 8.2mm taylor thundervolt wires and they are 40 ohms/ft. If im not going to gain anything im going to leave the ones i have. Or i could splurge and go with the 10.4 mm wires lol
