for what it is worth I wouldn't go over 20 ft/lbs My own preference has been using 16 ft/lbs That was in both my 99's with 5.4 and a 4.6 and my current 2001 with a 5.4
Again make sure you at least replace the boots and use dielectric grease on the wires also check the coils where the boot wire attaches and clean any corrosion
