I was thinking about buying one of these but a guy at the performance shop told me it was a waste of money for a basically stock car that was already equipped with a DIS. I think the ignition system on tauruses (96 and up) is strong enough on its own, anyway.
Gen 3s have a pretty strong spark already. I would only recommend putting that in after you have upgraded a lot of other stuff. Autolite's premium wires are about the best plug wires you can get for these, they are around 120. I used digital ignition in my escort, but I only did that so I could control my timing off of it, and since that escort had such a weak spark. But that car was turbocharged and used larger injectors and a larger fuel pump, so I figured it needed it.
