What years did Ford use 2 piece spark plugs?

Ford’s Use of 2-Piece Spark Plugs
Ford used 2-piece spark plugs in certain models and years. These spark plugs were used in the 4.6L, 5.4L, and 6.8L engines from 1997 to 2008. The 2-piece spark plugs consisted of a nut part joined to the electrode part, which could break when attempting to remove them. However, it’s important to note that Ford redesigned the spark plugs in 2009, and vehicle models from 2009 onwards do not use the original 2-piece design. The newer design is a one-piece spark plug that is less likely to break.
If you are specifically interested in the Ford F-150, it’s worth mentioning that the 2-piece spark plugs were used in the F-150 models from 2004 to 2008. These original spark plugs had a tendency to weld themselves to the cylinder head and break into pieces when someone tried to unscrew them, causing potential issues . However, Ford has since addressed this problem and the newer models do not use the 2-piece spark plugs.
