really? i thought they dropped the 4.2 v6 and the now available options are the original 4.6, and a 3 valve 4.6 that u can get with a six speed like the 5.4

Best thing to do is never change the plugs. As clean as modern engines run, and as hot as the spark is I know first hand they will make 200,000 before you notice your fuel economy decline. The risk to reward isn't there. I used to change them on our Prizm but I was taking out new looking plugs and putting in new plugs and the only reward was the risk of dropping shit in the hole or grrrrr'ing the threads. So I gave up the habit.
it seems that the trucks that were poppin plugs were from 97-03 range. has the 2 valve 4.6 changed since then?
i really wuddnt mind buyin a new f150 regular cab short bed(i like em alot) as long as i could be guarenteed some bullshit like a plug flyin out dont happen

No, they added more threads in the heads. 4.6's were never notorious for it anyway.
