Changed plugs today
Replaced the stockers with Denso Iridiums. First time I have changes plugs on a 5.4 before. Much easier than I thought it would be after reading all the horror stories here, however it did take 3 hours and 45 minutes. Next time I believe it will take two hours or so.
Truck does seem to idle a little better and start up easier. Otherwise there appears to be difference from the stock plugs. Chose to go with Denso becasue the next mod is the JDM 4# lower and chip!!
BTW, stock plugs were gapped at 0.044" and all looked to be in really good shape.
