Just picked up a 06 Taurus with 68k on it. It has the 3.0L cam in block engine, and still has the OE plugs in it. Do these engines perfer any spark plug more then others???

You'd probably be fine with Motorcraft or Autolite OE-style replacements. These are probably single electrode platinum plugs.

Also I have yet to find a "picky" engine that didn't do fine with Denso or NGK Iridium plugs, but for the OHV Taurus engine, it's probably not worth the extra cost for the Iridiums.
