Ok I used the search but couldnt find info on the 4.2 99 f150. Im using screamin demon coil pack, .65 gap spark plug and i want to use 10mm wires.. i cant seem to find any for this motor and year... has anyone else ever done this? Livewire set up... firewire... its been called a few different thing. thanks.

 

Try Summit Racing. They have a pretty good selection.

 

i couldnt find ones for the 99 4.2 only ones i found close were 2001-2006

 

Might need to get a kit and build your own.

 

only problem ive found with universal kits is, the ford clip on the end of the wires. none of the universals seem to have those.

i figured 97-03 would fit but they said 01-03 is a no go.
