Your engine is a 2.3L Duratec engine with only 4 plugs. The 2.3L Lima engine has 8 plugs and 2 coilpacks, as stated before.
The first time before I unplugged the wires from the coilpack and removed them from the spark plug wells, I draw on a piece of paper how the wires ran from the coilpack to each cylinder. Something to keep in mind in order to not mess with the wire order.
In order to remove them, disconnect the end from the coilpack and then give a little twist to the end by the cylinder, and just pull it straight out. Do not pull it out too hard, just pry it gently.
I recommend you to use Autolite/Motorcraft plugs and wires. I replaced my original wires with Autolite
and 15k miles later they've been working fine with no issues at all. Plugs are Autolite as well. I've tried Platinum
, Double Platinum
plugs. Right now, I'm running Copper plugs.
