Time for new plugs
I have a 2003 4.0 Ranger with 186K and I'm still on original plugs. What will be my biggest concern in attempting to replace? Do these plugs break easily when trying to remove? If they do break, what tool is needed to remove?
Shops around here want way to much money to replace so I thought I'd take a stab at it or would I be better off letting them do it since it has been so long?

cross threading is catching the wrong threads killing them. i would recommend soaking them with some PB so they come out easier. if they are the original plugs i can bet they are the original wires to. change the wires

if you've never done it before get someone who has to help you out and do plenty of research. it isn't hard but for someone who has never done it before I can see mistakes being made. you should also be able to make sure they are gapped correctly.

remove the wheel and inner wheel well liner on the passenger side to get to the plugs much easier. its a pretty straight forward job. and no, these plugs are not prone to breaking. make sure to get the right plugs though, call ford and get the right part #. someone here might know the part number as well, this topic has come up a few times before.

the only thing that would brake on the ld plugs would be the ceramic, not biggi woudln't effect it coming out, and just as long as you start it by hand even with the extension you should be good obviously if it gets really tight really fast is cross threaded and at that point back it out and try agian, DO NOT FORCE IT, EVER!!!!! and make the new ones snug, DO NOT KILL IT!!!, if you over torque it you can completely strip out the treads, spark plug becomes projectile, engine wont run, tow to garage, to get re-threaded, point in turn just snug them, thread them in carefully, check plug gap, do not drop plugs, and do not bag them a against the block, if you think it went in the hole but didn't go in very far don't force it, use an air compressor to blow the rust and dirt away form were the plug is so you don't get any dirt in your engine, be gentle with them, good luck, if you have any further questions be sure to ask

I'm changing plugs on my 98 Ranger. I went to the Ford stealership to get them because I read that the Left and Right side were different. The Parts Guy gave me AGSF22WM (SP-479). I asked about the two different types and he said Ford replaced with this new single part #.
Thanks for the tip to remove the passenger wheel and liner. Sounds like a PITA.
I've also heard that putting on a bit of Never Seize on the new plugs will help getting them out in the future so I'll do that too.

if you use anything use the stuff that's made for plugs, they will probably throw you a free sample pack if you get your plugs from an auto parts store, they did for me. it keeps them from sizing and they stay tight, i used that stuff then took the plugs out later dwon the road, still as tight as i left them but threaded out easily
