For any threaded fastener (or spark plug in this case), I find that turning the fastener backward until you feel the fastener drop slightly (when the starting points of the threads pass each other) puts the fastener in a starting position where it’s harder to cross-thread it.

If they do, they didn’t start doing that until after 2009…my manual for my Focus specifies Motor Craft SP448 and even includes the gaping specs
**use a good plug socket that has a plug holder inside of it **
Let me be more specific . . .
I believe Autolite makes the oem plugs that Ford installs at the factory
Yet those plugs don’t say Autolite on them
I have no comment about the spark plug gap

Spark plug / OEM history question:
Hasn’t Autolite long been associated with Ford; Champion with GM; NGK or Nippo Denso with most Japanese marques; etc., etc.?
What for Chrysler and other carmakers past and present?
Chrysler uses Champion spark plugs, Gm uses ACDelco.
I would agree with some of that
In some vehicles GM has been specifying NGK plugs. ACDelco use to be part of GM, but that’s long gone.
Got them changed today. The car runs without kicking off any codes, so I must’ve done OK. Thanks for your help.
