I run Champion Platinum plugs in my V10. Wires just a good set, not the cheapest you can buy. I have had good luck with Duralast wires from A.Z.
As for oil I like Napa 10-40. Napa oil is Valvoline. I like Rotella oil also.
I'm a firm believer in running OEM brand plugs, fuel pumps, etc. Most electrical & fuel parts. I have a Blazer 4x4, if you try to run aftermarket plugs, caps, rotor or fuel pumps FPRs etc. If you don't run AC Delco, or Delphi it seems to always be an issue down the road long before there should be.
The OEM plugs for our V-10s are Champions. When I bought mine last year I never checked what was in it. The truck had only 74,000 miles on it. So I decided one day to look at the plugs. It was clear they had been changed because of being Platinum. Dodge didn't use Platinum plugs in our V-10s. But they looked real good nice & clean etc. If it would of had another brand plug I would of changed them out for a Champion plug. Just my opinion.
