At least at or about 20,000 miles change plugs Champion 7440/7570 gap at .040, Chrysler Preformace Wires P 4876511 ($48) or Magnacore from Race & Street.
Use dielectric grease on plug wires and anti-sieze on the plug threads.
They are not hard to replace, remove Intake and use a bungee cord to hold it out of the way, and remove/replace one at a time. Theey are torqued as well as the 5 bolts used on the intake. Not sure of the torque specs for either. Maybe someone else can give that info.
