Will work on most all of Ford's 4.0 v6 including Lincoln Mercury and others for sure. Specifically out of a 2002 Ranger, these used NGK plugs look so good, I decided to save them as backups or to replace some nasty China plugs. Don't get me started, ah ha.
The idea is to save you money and get you back in the fight.

If you have an old 4.0 v6 with nasty plugs, this is a cheap fix, these used ngks, I would take over a junk new "fire" plug any day..
Wrenching since the 70s, I've seen my share of nasty plugs.
As pictured.. 6 used NGK plugs for 10 bucks. Beats a bucket full of new junk plugs.
I gapped them to match the Bosch plugs, I am not a fan of these new excessive gaps such as 0.062 to 0.065" , I usually tighten it up a bit.
How does gap effect the arc voltage?
Also, I changed the difficult ones, 3 passenger side, as the (other) mechanic only changed the easy 3 on the driver's side, if you need help, let me know. They are tricky on the passenger side.
Frickin a/c always in the way. Carry on.
