    has anyone tried any type of iridium spark plugs on the non turbo 3.5?
    I´ve seen that the 3.5 Ecoboost people have tried the NGK IX Iridiums, but I haven´t seen that on the na 3.5
    Any benefits like better fuel economy or more throttle response, etc over the stock platinum?

    Original motorcraft are your best option, maybe autolite. The "right" plugs might not work out so well. Can't go wrong with motorcrafts!

    Any performance gains would be due to replacing worn plugs.

    I used iridiums in the 3.5 NA. Ran just fine and should last much longer than the stock ones which did not even make the 100k change interval ford recommended. Did not see a difference other than solved my misfire problem.
