I know there are issues with spark plugs breaking on the 2004 and up 5.4L F150s, but are there any known problems with spark plugs breaking on the 2V pre-2004 Tritons? I have a 03 Supercrew FX4, and I recently passed the 110,000 mile mark with as far as I know the original plugs (bought truck at 46K miles.) Some people may frown on me for not having them changed sooner, but the truck runs great without any problems. Fuel mileage about 16.5 on the avg. and about 19 on the highway. Just wondering if I should brace for a disaster at the dealership. Thanks in advance.

Not like the 5.4l 3v units. Some plug blow outs on 03 & early 04 2v 5.4 2v.
If you follow the Ford tsb for plug removal on 5.4 3v units much less chance of breaking a plug.

 

Alright, thanks. I found a Ford dealership that quoted me $90 for the labor on changing out the plugs. Sounds like a good deal to me.
