Updated sparkplugs in 08 ?
Hi all, i have been reading here on this site about all the spark plug issues on the 5.4 3v Triton. I have read that this engine was updated to a different style of plug to eliminate the breaking of the plugs in the removal process. What is the engine build date that these engines were updated. I have heard several different dates. Thanks

So nothing specific on the build date. According to the post........
"about 1/2 the 2008 production run is the old style of plugs
but yes, the later 08's have the 09+ plug style "
and
"From what I've read, 5.4 3v engines with build dates (that's engine build date, not vehicle) after 10/8/07 got the new heads with revised plugs. The engine build date will be on the tag on the driver side valve cover. "

From what I have read if your boots are brown you have the new plugs.
Black boots you have the old design with the removal issue.
