I have an 08 f150 with 141k on factory plugs and I want to change them, I've looked and my engine was built after the build date changed, so does this mean I don't have the problem of spark plugs breaking off? Or do I still need to worry about that?

 

I would still be careful. crack them a little bit and then spray some penetrating oil to loosen it up. they could be pretty stiff after 141k miles on them

 

Ok thanks! Yea I can't take any chances since she's my dd

 

Still be careful.. But you Should be good to go..

 

141k you probably don't have much of a plug left in there. Mine were worn down at 45k

 

Changing the spark plugs on our trucks is an easy task. Easier than you think. Kozal01 has a great write up on this.
