This answer was rated:

what year did ford trtion v8 have a problem with geting spark plugs out, and what year did they fix the problem?
Hello, My name isXXXXX will do my best to assist you. The range of the problem was 2004 - early 2008 Vin #5 or the 8th digit of the VIN. I have not run into but one 2008 with plug removal problems but surely have 2004-2007 as well i own a 2004 VIN5 and had the problem at 60K where 2 broke in the head. was able to remve them without pulling off head. IMO? the 5,4 VIN 5 was not a good engine fro 2004-2007
