My 4.7 didn't like them as much as the 5524's
I replaced the original plugs with 3923's due to the dreaded ping. They
solved the ping, but it felt and sounded like i lost a little power. three
months later and i swapped in a set of 5524's and the engine was more
responsive and no sign pre-ingition.
