No, they do -- the 2v plugs were updated, I forget when but it was around 2005 or 2006. I remember when I bought them for my 99 V10 I had to check I had the newer plug.
(Nothing related to the 3 valve heads at all. The non 3-valve heads had plug spitting issues! This issue goes back a long time. 3 valve heads had their own spark plug issues - spark plugs breaking off)
But if you look up the plug numbers these days, the plug number you will get will be correct.
e.g. Part number for my rig (2002 V10) is now
AGSF-22W-M, Motorcraft SP-479.
The newer plug number also has a different plating. But definitely look up your plug number on FordPartsGiant.com or wherever has a current Ford catalog.
(the original OLD number was AWSF-22E -
DO NOT BUY!)
My point is don't buy non-OEM plugs at a parts house because they may have been cross referenced to the older plug.
There are huge threads about this over on Ford-Trucks.com if you want the chapter and verse.
Just search on the spark plug numbers.
I forgot to mention (obviously) you have to remove all of the air intake tubing.
My other advice is don't try and do them all in a day. I would do one or two, take a break, come back another day. Super annoying job in a van. In a truck it would be a piece of cake.
