I have Motorcraft Double Platinums. They are ~12 bucks each, but I got them at cost for 7 and some change each. They're the same ones Ford put in mine originally, but they run pretty smooth. I have the Accel coil and Magnacor wires and didn't get any real horse power gain, just a little smoother idle and better gas milage, so don't expect a kick in the ass acceleration or something.
