well i have bean on here for some time reading threads
i did my plugs the other weekend finally 05 fx4 5.4 with 140k on it i had bean putting it off now for the last bit broke down and got some plugs witch worked out well only got charged for 4 of them and i had pick up lisle the other week from ebay and went at it only broke on plug on the back drivers side every thing else came out not to bad i did it on a warm motor and with my bosh 18v impact on drivers side front two and front 3 on passenger side the rest i wrenched out was under the hood for about an hour doing it this way
only reason i can see i broke the one was that my motor had cooled down by the time i had got there but its done with and happy it all went well and it only was about an hour of work for me to get it done

 

Cool!

 

That's a lot of miles! Good job.

 

Good job. Bet the truck is thanking you.

 

oh it is but it is still running a little ruff at times and for the most part there was not really much for carbine on any of the plugs but i do drive the truck a bit hard and as i see it from other cars or trucks i have had over the years when i first get them they like to blow black for a bit when i start driving them till i them cleaned out then they run great again
