The Autolite 5224's (and 5223's) are exact replacements for the "Special
Extended Tip" plugs that come in the Magnum Engines. However, the 3923's
seem to cure the pinging (in some cases) much better than the 522x series
plugs. There's also some Dyno proof that the 3923's actually increase
Horsepower by about 4-5HP.

Subject: DML: Autolite 5224 vs. 5223?
Ok, I know autolites have been discussed alot in the past but please bear
with me as I am having trouble accessing the archives. Anyways, I just
bought a set of 5224's for my '99 5.2L but have yet to install them. My
question is, should I try to exchange them for 5223's? Because I understand
that the 23's are one range colder and god willing might help my pinging
problem. Are the 5224's the same running temperature as the stock plugs?
By the way, I am running magnecore 8mm wires, brass cap and rotor, and
bosch platinums.
thanks for the help
