Saved a few screenshots from the Owner's Manual if anyone wants them, pretty sure you can still download it online from Ford though if needed...





But hey,

(1)- does anyone know why the listed spark plugs aren't the exact ones they show at the Ford dealer to go in my 97 F150? They always give me ones with AGSF 22FSM stamped on the side... they seem to work ok, so far at least. lol

(2)- also, anyone have the missing data handy I can fill in the chart with about the Torque and Horsepower of the stock 5.4L by any chance?? Would be nice to have...

 

The AGSF 22FM is the revised spark plug that is nickel coated. I have switch to NGK iridium IX they last longer. As far as the power goes the is should be 220 and 305 if i remember correctly

 

The revised plugs have nickel-plated threads and are fully threaded for compatibility in both the 4 thread and 8 thread heads.

The 1997 5.4 specs are:

HP - 235@4250
TQ - 335@3000

 

cool, thank you!
