Do I need a special socket to pull the stock plugs or will a regular 5/8 plug socket work? I'm putting a set of the one piece champions in before I have a problem...

Technically speaking I think the proper size to use is a 16mm but a 5/8" should be close enough. Be careful though because I have heard of people breaking them off while trying to replace them! I am going to change mine out but I am waiting until winter just in case I have to pull the heads...

Ford does have a special socket to remove the spark plugs--I know this because I just borrowed one from one of my ford techs to replace the plugs.

I changed mine last month. I used PB catalyst on them. It soaked for 10 minutes and they came out easy.
Put some PB catalyst on them and let it soak. Break them free and turn one turn. Add a little more PB catalyst. By then mine were able to be turned by hand. Dont overdue it with the penetrator spray or you could hydrolock the engine. Also when putting the new plugs in use some Permatex high temp anti sieze on the flat area above the threads. Dont put any on the threads or you will be wet torquing them when you torque them in.

You will need a 9/16" spark plug socket to pull the factory plugs and a 5/8" spark plug socket to install the Champions.

I just did my spark plugs in late April and no issues taking them off, my car has 27,000 miles on it and I do drive it like I stole it. I only changed them since I was putting in HTO plugs for my supercharger install. Only two of my plugs had build up on them and even at that it was very little. I do recommended you use a shop vac or air compressor to clean out each plug well while the old plugs are in before you start. Keep the dirt out.
