Agreed, they are 'quality plugs', but they aren't the 'correct plugs'. The Motorcrafts are a (dealer quote) "fine wire-low resistance plug". I tell ya man, I about pulled my hair out over this. I was seriously going to trade the Tour in. I'm not sure if the V-6 is the same as the I-4, but I'd bet it is. A call to your dealer and a KNOWLEDGEABLE parts guy can't hurt. If he tells you that your motor requires a fine wire low resistance plug, you know what's wrong.
Ken, 99 Silver Frost SE Zetec Atx, polished alloys, Kumho's, Pioneer hi power CD/AM/FM. Factory spoiler (added) Audi side lites, Borla stainless steel muff. Stolen, recovered in pieces. Looking for another Tour, preferably V6, 5 speed.
