I want to go with a higher grade plug from Motorcraft, but haven’t been able to find any for this engine, yet.OEM plugs.

I just went to the dealer. They said the only plugs they have listed for this engine are platinum and were about $3.50 each. They recommend changing them after 100,000 miles.Double platinum should go 100K, but I'd replace them at 75K.
Iridiums will go farther, how much farther I don't know.
I gotta ask though, what's with all the threads lately? It seems like most of this could have been handled in a single thread.
If the goal is simply knowledge for knowledge's sake, then yes. But when I see ten or twenty different threads from one user all pointing in one direction over the course of a week it makes me think "Is there a bigger question that isn't being asked".I think the separate threads are good for people searching in the future.

That's pretty standard for platinum plugs. The OEM ones are mileage based as well but I can't remember what that is. It took me until last fall to hit that mileage with my 2011. Not a horribly short time period but it depends on what kind of mileage you expect to be driving your truck. Whatever you decide to go with, I strongly recommend you look up recommendations on how to change the plugs. Not getting at them at the right angle can make the job miserable. On the passenger side, I would highly recommend you go through the wheel well and pull the splash shield to do it. Coming in from the top is doable but a completely miserable experience with the back plug.I just went to the dealer.

All the threads because I thought I should separate everything into more specific categories. Should I have combined everything and posted in the general tech forum?
That's a key point to why I registered here again with my current Ranger. As far as I can tell, 2010 Ford Ranger 4.0L should have Motorcraft SP498 plugs. Which are according to another forum, OEM spec. They are really double platinum. All the stores I found claim they are NOT compatible. Double platinum makes sense to me noticing the spec of the coil pack - 3 coils on a V6.Well, which ones and why?
