On the last trip in the RV on startup there was a slight miss, could clear up pretty quick (no codes). Only has 71k but is 15 years old so everything is factory. Rockauto nor OReillys list a AC-Delco Iridium plug so I figured it was a double platinum like our other cars around the same year. I was wrong! 41-985 is the factory plug but from what I've read 41-111 is the replacement. The problem is I've already ordered 41-962's off of Ebay. Also ordered AC-Delco's wires. Might of wasted a bit of money but everything has to come apart anyways since there's a broken manifold bolt on each side.. that may be for another thread.
Pretty sure I'm just going run the 41-962's as I doubt there will be any difference. Unless anyone can change my mind.. NGK from google research is what a few run in their 6.0L's but I really prefer to run AC-Delco plugs.
