4.6 spark plug wire failures.
I began to shop. Eventually I wound up with a couple Terminal ends for the wires.
I replaced the #4 wire and the problem went away. Then #3 and #5 failed.
I'd guess that all of them will fail eventually.
I put new terminal end on #3 and the problem quit.
The Ford ends rust. The wires are OK at the Distributor, it's just those Rusty terminal ends.
I can't drive it this way. I need some terminal ends.

So...do any of you guys know where I can get some terminal ends?
I've been online to a lot of (MSD, Summit, Moroso, O'reilly's...) places but they want to sell wire sets.
I just want Terminal ends.
Help!
I cant find a F mark on the wires so you are probably right.
They have lasted the three years I've owned the truck though.
The wires are good. All measure 7 Kohms or so.
I'll just replace the ends.
