Wow, that's pretty conservative. My 90 E150 had lots more than that when I finally shed it (for no other reason than I wanted a 4x4). I better get the same out of this one!! Anyway, I'm looking forward to the answer about the 06 5.4 plug thing too... just curious...

 

Conservative is right.. I have Always owned used prior to this being my First new vehicle... I guess 120-150K is my sell point to buy another new F-150

 

Ah, it was the 'until it drops' part that got me, made it sound like you expected its' death at that point, rather than its' trade in point. Got it.

 

Yes it is the 5.4

 

Just picked her up!!!!!!!!! No broken plugs and they are in good shape, not much rust or carbon on them...........I probably could of waited to change them, kicking myself now that I spent the $.........I kind of wish one of them broke while they were changing them, would of justified the money spent. Oh well I just should of had more ***** and changed them myself!!!!!!!!!!!! I can say this now that the job is done and none broke!!!!!!!!!!!!
