well i feel that i should replace the spark-plug wires for some reason, i suppose its about that time? i dunno- if i replace the wires with some from the folks at Ford Racing, it would also make sense to change the plugs- since your there. but what plugs to use? should i do anything-else while im at it? (yes i would love to add turbo's headers and gobs more stuff, but we don't wanna get that carried away? or do i?)

I'd say replacing the wires is almost pointless. The mechanic at the place where I dyno has a 600 HP stang with stock wires. He believes my car was missfiring because of the new wires, but who knows.

I have the MSD wires and I felt they did make a difference in smoothness of idle and in a little better pull at higher RPM. Nothing dramatic, but I would buy them again.

Most people are running stock spark plugs, so unless you have a lot of miles why replace?
