The yellow Accel plug wires I had were in pretty good shape still. It was running decently with those and the vee type platinum plugs that were in it from years ago. I still decided it was time to change. After reading a little on the site about plugs, I decided to go with the copper electrode ones for a '93 Cobra.
Gapped around ~0.044"
I also got a set of 9mm Ford Racing spark plug wires. I thought the red would look good:
And they do!
I had pulled all of the wires off at once and followed the Haynes manual for the firing order of 1-5-4-2-6-3-7-8 for re-install. Not quite right (and you could tell by the mis-fires). The Haynes didn't specify the HO/351W firing order of 1-3-7-2-6-5-4-8 which mine is. Idles MUCH better like this
