There is nothing special about these engines, they dont need anything fancy. Your best best is to simply use champion copper type plugs. Or at least you should use a good name brand, copper type plug.

Do not waste your money on platinum plugs or E3s, good ol' Champion or Autolites will work just fine.

Most parts stores will have three choices of wires, economy, mid line, and premium. I try to stick with the premium wire set from NAPA.

I have the Performance Distributors ignition upgrade on my V8. It includes a Screamin' Demon coil, 10mm Live Wires, Brass terminal cap and rotor. They recommend one heat range colder plugs as the Coil has a more powerful spark compared to stock so I have Autolite 3923s for plugs gapped out to .065" per recommendation. I also went one heat range colder because of my SCT Tuned JTEC.
As for the I6 I am running the premium wires my local auto store sells with brass terminal cap and rotor and champion plugs.
