Xcop EFX, they make a setup for the Duratec V6

interesting system. I assume this replacing your coil pack. There may be a small gain here, but I highly doubt anyone ever saw 200HP increase like they claim. I was thinking more like 2-5hp at the most.

If not it is just those cheap old wires with a capacitor they sell ebay. Those wires ruin engines.
 
Replacement coils or coil packs are usually just placebo. Most modern coils will keep a spark above 30PSI. It's only when you go to the extreme pressures that you need more coil power. WX is just trying to cater to the COP crowd since they can't sell them a set of overpriced wires, IMHO. Save your money for race gas.
