The 5224 (normal heat range) is listed for the 5.2L and the 3924 is the
normal heat range listed for the 5.9L.
Because I'm looking for any improvements under track conditions, I opted
to put the 3923 (one range colder and listed for the 5.9L) in my 5.2L
Dak.
I didn't see if there was a one range colder plug for the 5224.
Hope this helps.
