Although I would not recommend them for the Duratec, the Denso Iridium plugs are hardly crap. They won't give you any measurable horspower, but they are a quality plug with material that lasts longer than platinum. But, it is a single-sided iridium which means it does'nt work with the Duratec's reverse spark DIS system.
