I bought it and a set of Ford Racing wires for only $50 because the company I know was clearing out their inventory. I figured what the Hell, at that cheap, what is the most that I could lose. I have driven with it for about 35,000 miles and didn't really notice anything super about it. But then again, that's just my judgement call.
From what I've researched, just the coil and wires by themselves are going to give a minimal gain as the stock ignition control does not support the multi-spark capabilities of the hardware. Which is where the MSD ignition control box comes into play -- it allows the car to take full advantage of the technology and give that "bigger" multi-spark which will burn the fuel more efficiently and completely.

This one through Andy's is expensive -- I have seen them floating around on eBay for between $150-$300.
