2 or three years on mine with no issues, forget exactly when I put them in. Got tired of playing whackamole with misfires, changed the originals out, no more issues with spark.

Perfect, that is what I like to hear. I am going to make the move on switching them out next week.

Of course, after I make this thread, I stumble upon a thread asking a similar question, and most of the responses were to look for a 2009 coil since the head design of the 2008 changed, and is the same as 2009

It depends on your engine build date.. 5.4 3V built after 10/09/07 will have the re-designed heads. Not all 08's got that motor.. a sticker on the valve cover will have said date and it will also have Brown COP boots vice Black.
