It's the 4.6L's too. The Mustang has that problem. I heard the 08 Mustangs came with a one piece design tho. I'm sure Mustang owners change their plugs more than F150 owners since people mod the crap out of Mustangs versus F150's.
I'd either change them to one peice when the truck was brand new, or leave them in there forever. You don't need to change them til well over 100,000 anyways and are you gonna keep it til it has 100K. I wouldn't. I've got a 97 F150 with almost 124K now. My Dad's 03 has 135K and they are both still running strong with original plugs. A friend of mine has a 97 Expedition and he changed his for the first time at 300,000. He's got 330,000 on it now. He runs a delivery company.
yeah im nervous about changing them in the 07, ive heard about them snapping
