My truck
07 4.6 xl triton utility bed super duty rwd.240k

ive heard of the spark plug breakage issue with our trucks but is it only on the bigger motors?
or du I have to worry when I do mine?

 

I believe that's only an issue with the 5.4L 3 valve engines from 2004 till late 2007.

 

Only 5.4. Go crank away and rip those plugs out!

 

Thx guys!!

 

Yep, your 4.6 has one piece plugs that wont break

 

So I’m on for the plugs this Thursday...
service manual doesn’t say anything about removing anything...
so my question is ...
do I have to remove these rails to get access?(see pic) or is there enough room to slide the coils out and then the plugs?
