Resistor spark plugs vs. low resistance plug wires
Forgive for asking in C4 tech, but I never have any luck in the other cars section. My '94 Dodge Dakota 5.2L (318) V8 uses Champion RC12YC "resistor" spark plugs as O.E.
I'm going to change the spark plug wires and was going to install a low resistance spiral core type (after market type that suppresses RFI) instead of the O.E. carbon core high resistance type, but I wonder if using low resistance wires with resistor plugs would be like taking a shower with your clothes on?

Nothing wrong with using low resistance wires if they are the spiral wound anti RFI type as they will have the same effectiveness preventing plug noise in your radio. Resistance wire or spiral wire have very little effect on the spark energy, so either is fine. Spiral wires are more durable (resistant to mechanical movement causing a break in the conductor). You are doing everything right so far, congrats.

sticking with the resistor plugs shouldn't cause you any RFI problems. Any EMI(causing RFI) generated by the spark plugs will be shielded by the surrounding block. The wires are the main component of EMI, and these guys are all over the place under the hood. RFI has always been a problem since the introduction of HEI...........FYI
