The 392x series are listed for the 5.9L but can and are
being used by many on their 5.2Ls for that few extra
rwhp. The 3923 is one range colder than the
OE Champion plugs used on the 5.2L.

The 5224 is a truck-type plug (bigger central electrode)
listed for the 5.2L. The 5223 is one range colder than
the 5224.
