The ignition system is MORE than enough for most all drivers/cars (tours) out there.
As for wires, the 9mm FMS Racing wires are a hit and miss (no pun intended) type of thing. Some have had 0 issues, others have had tons.
Personally, the 8mm Motorcraft OEM wires are the best bang for the buck, and work just as they were intended (the preferred replacement by me...)
