ANOTHER SPARK PLUG QUESTION
I have a 2008 explorer with a 4.6 engine. What date code did ford change to the newer style spark plugs, one piece. The tag on the valve cover said the engine build date is 220408. I think this is May 22nd of 2008. part number of the engine is 7S302AC.
Does this engine have the 2 piece or the one piece plugs.

Compare your door pillar sticker build date to your valve cover. 4.6L 3V before 11/30/07

Brown coil boots are used on the newer 3V heads. Black coil boots are used with the older design heads with the two piece plugs.
