Go with the factory Motorcraft plugs or a set of NGK Iridium for that application, another good choice would be Denso iridiums.

Really depends on if you're modded at all svtallday. Typically if your truck is unmolested then stay with the stockers. If youve added any addiditonal boost (4-6lbs) then most that have go with TR6's gapped somewhere around .32-.34.

You're still looking at .032 - .034 being your best bet for that boost range.
