Ok I visited my friends at the parts store today and compared the 3923 to
the 5224 autolites. the 3923 are for the V-6 not the 4.7. the list shows
3924 actually for the V-6. so you men are running a colder plug. But the
important point i found comparing them is that the 3923 threaded portion is
slightly shorter in length than the 5224, Meaning if i was to install the
3923 in my 4.7 the plug is actually up inside the plug hole, THUS causing
the electrode to not be further down where it should be. Would this not
cause a problem in the way fuel air is ignited.? I dont want arguments
here, I just want to say I disagree in using a plug in a motor in which it
is not engineered for. The correct plug for the 4.7 is the AP5224.
A=AUTOLITE, P=PLATINUM.
