When I first became a Ford Modular Motor owner and joined a few forums I was alarmed and a bit scared there was an epidemic of plug failures in these engines. Turns out that's simply not true even though those going through a repair might not agree which I understand.
I then happened across this thread on FTE:
https://www.ford-trucks.com/forums/1...ead-heads.html It was eye opening, forever relaxed my concerns about plug issues.
While that "test" wasn't conducted strictly but it does cover enough different scenarios to show how uncommon this really is.
Just my humble opinion so take that for what it's worth.
