2005 and it has 230K on the clock. Only reason I am thinking about it is because the cop look like oem. I wish I had someone on here that had access to Ford service to run vin for info. The cop have the writing on top of them with a yellow slash line on them. That is why I think they are original.
Hopefully they arent and have the new style in it.
Along with the spraying run a bottle or 2 of seafoam thru the gas tank before hand. It will eat the carbon ring buildup off the bottom of the plug that protrudes into the cylinder and hopefully come out easier.
We did that along with the penetrating oil (twice) on one with 160k on the original plugs and they came out easily.
