RC12LC4 I think but it should be under your hood on the emissions sticker. Use 3923 autolites they work much better and help prevent pinging.

The Autolites worked well for me and now I have NGK ZFR6-11 plugs and they are working just as well. They are same length as stock but one heat range colder like the 3923 Autolites..

I have some Platinum Split Fires in my 5.2L. I don't really have a comparison to go from, what does everybody think of these as a performance issue? Any good or just hype?
Should I switch to the 3923 Autolites?

If your truck is stock and doesn't ping excessively, AC rapidfires work well, stock champs work well.
If yours pings, I currently am using Champ 4412's in my 5.9 and prefer those to all others I've tried. 3923's gave me a power loss.
Wanted to try the NGK's but they didn't have those - how are they working?
Some trucks respond differently to plugs due to mods, weather etc.

Ar3923 or ar3924 Autolites are the ticket.
