Ok after the shock of finding out ford changed the part # on the coils and then almost doubled the list price I've been looking around for some coils for a good price close to what we use to pay for the same part. I found someone selling some with the part #'s DG-490 & XW4U-12A366-BB and say they will fit the 2000 LS 3.9 V8 engine but I wanted to be sure before I order them. Does anyone have a clue as to why Ford changed the part number and double the price but more importantly will these work on my car.
