I have had a slight skip at warm idle, nothing bad but I want it gone if possible, so I pulled out my Champion truck plugs for inspection and two of them broke. Looking and calling around, the old 4412 plugs appear to be discontinued. Autozone said they had a $.50 clearance sale and they are all gone, while NAPA lists a Champion dual-tip platinum as replacements. So FYI folks.
I decided to install a set of Autolite 3924 which are for the older inline six engines and they seem to be working just fine, maybe a little more miss at cold start but they seem to run steady at warm idle.
