Default Changing spark plug wires

Hey, I have another (probably stupid) question, but how necessary is it to change out spark plug wires? I've had multiple vehicles with over 100k and my last one I sold at 200k after I put 100k on it and have never changed any spark plug wires. I've always understood this as a performance mod, or replace when broken, have I been starving the ol' girl with poor spark? I intend to change the plugs shortly as I have 113k on her and I'm doubtful they've ever been changed, debating on doing the wires also. Thanks.

Over time the conductivity starts to break down. Going bigger with a wire is usually just decrease resistance.

So for a daily driver that's never seen a drag strip or super deep mud is it a necessary thing or more something just to say you really baby your truck or something? And if I were to do it, any brands to go with who would make a lime green cable for me by chance?

No, replacing the plug wires is actually in the maintenance schedule every 60,000 miles (listed as 'ignition cables'). Like I said, wiring tends to break down and increase resistance over time and use. That's probably why they tell you to replace them every 60,000 miles (in both A and B schedules).

If you are planning on replacing the plug wires, I would seriously encourage you to swap to the Taylor Shorty wires, they will turn the dual coil into a single coil so you'll have a burn similar to the '06+ rather than the off-compression spark that the early hemis used. It was an attempt at clening out the combustion chamber oon the off-cycle, but it never really did anything.

Can you expand on this a bit? I'm coming from a long life of Chevy engines with 1-plug-per-cyl and a distributor, but I understand ignition systems fairly well...including many motorcycle ignitions. This is my first Dodge ever and obviously my first hemi. Not being familiar with the different systems in different year models of hemis, are you talking about a spark cycle that is occuring when a given cylinder is in its exhaust stroke vs. a spark not occuring at that time? Many motorcycle systems have coils with dual leads, and there is often a harmless and maybe even beneficial spark during the exhaust cycle in a cylinder. Does my '12 hemi have 2 coils per cylinder, 1 coil with dual leads, or what? And how does this differ from the earlier model you mention? And exactly how does the plug wire swap you mention work in this case? I know I could do a bunch of research and come to some conclusion on these questions, but it sounds like you're already familiar with these issues. Are you saying there's a benefit in doing away with the exhaust cycle spark, and if so, why?

I looked at the Taylor Shorty wires and I like what they have to say about them. Hard to find though... They mention that the loom tray removal is optional, do I need to do this, or what exactly is it? I've never heard of the loom tray. I, unlike the previous posters, am not very familiar with ignition systems. Walkin in the dark here. lol. Thanks!
