Late model 08 question

I'd say just pull the easiest plug to get to and see how many threads you have in the head, although I think the thread issue was fixed back in 2001 or so ( I'm probably wrong). . As for the plugs themselves, the latest part # is SP546 from Motorcraft (don't use any other brand, not even Champion). Not sure about the updates to the COP's.

OEM Ford MotorCraft Parts (click here)
Use your VIN to locate the exact part for your Ford.
I see how most people believe that you have to use MotorCraft. Especially with ignition parts. I will toss in my 2 cents, and tell you that I do not. My truck is using aftermarket parts just fine. I believe that while most over the counter parts in auto supply store just don't work well in Ford engines, you can use other aftermarket parts which do work well. I'm currently using E3 spark plugs without an issue. Autolite, MSD, Denso, & NGK have worked for me in the past with other Ford engines.
Do not follow my lead and install an aftermarket part, just to see what would happen. I encourage you to use MotorCraft, if you are worried about something not working. You don't need to experiment, just to find out what works and doesn't work. MotorCraft parts are not the most expensive on the market. Not a good idea to spend twice as much, or try to save a little, only to have problems. Use your best judgement. I see spark plugs from $1 to $10. I've seen ignition coils from $12 - $125. Even wire sets can run from under $20 to over $100.
In case you're wondering why: E3 spark plugs were eighty-eight cents on Amazon. I didn't expect to gain power or mileage like they advertise. But for that price, it was a bargain. I figured that I could always change them out if they didn't work.

There are people who swear by using only Ford MotorCraft parts. They will quickly point out that your AutoZone Duralast parts are the problem and that you should have used MotorCraft.
Not me. I use aftermarket parts all the time. And I don't believe that OEM Ford parts are the best. Sometimes, you can do better with aftermarket parts. Just not AutoZone Duralast. RockAuto carries a bunch of coils listed as "standard replacement". And if cost is a factor, they also have very low cost "economy" options. You get the idea that you get what you pay for. I would not recommend installing an ignition coil which only cost 1/3 of the price.
