There has been a lot of talk about coil packs and going with factory or not going with factory. I have a 99 f 150 with a 5.4 I have 1 coil pack going out and had one go out i want to replace all 8 but I am curious if i can go with the 60,000 volt ones I dont have any thing performance done to my truck I did a gear swap thats all I want to get the most response out of my truck. I have autolite double platnium plugs anyone have any thoughts if i can go with the high voltage plugs without messing anything up

 

For best performance, use only Motorcraft plugs (NOT Autolites) and OEM style cops.

 

get your coils on e-bay they are coil on plugs or cops. You do not have coil packs. Search "DG508" in e-bay motors parts section. Global and Uneek supply have been good to the members here.
