I’m buying new coils and plugs for my truck and would like to know everyone’s thoughts on the coils I’ve narrowed it down to. I will be ordering in a day or 2. The plugs I replaced previously with some cheap ones. But obviously I’d like to get some new ones again.

 

Don't buy aftermarket.

How did all 8 of your coils all of a sudden fail?
Unless you have problems, no need to change coils. And like above, aftermarket tends to be less reliable than the Motorcraft parts. You can purchase one or 2 Motorcraft to replace the ones giving you a problem for the same cost and maintain reliability.
Can't you find motorcraft plugs for cheaper?

 

Ford/Motorcraft ignition parts only for these trucks, anything else is a step down.

 

$72 for 8 Motorcraft double platinum plugs and unless the coils went bad you do not need them.
I have always bought Motorcraft or Autolite for my Ford vehicles, if I am working on my Neighbors Ram I get Mopar and if I need to work on anything GM I send it to the dealership so it doesn't rub off on me

 

hahahaha

 

So what you’re telling me you’ve changed only one spark plug when you got a misfire? Or bought one tire instead of two? If one goes out they are all bound to go out at some point… I’ve had cylinder 5 misfires for sometime and I shouldn’t because they are newer plugs. Maybe 15k miles on them. But I put some cheap ones in. Also every time I got cheaper I end up doing the work twice for twice the cost.

 

“cheaper” has never done me any good. That’s why I’m spending money. I’ve been having misfires at random for some time. It’s always been cylinder 5. With a few others randomly popping up time to time. But 5 has always popped up. Some days it runs great others not so much. Long tube headers, cats and glass packs are next then cams 🤙🏻

 

COPS are not a wear item, they don't break down over time. They either work or don't work. I'd replace all plugs, then see if the misfire continues. Replace that COP.

 

Spark plugs are a wear item and I would change them all together.
I would never change a coil/coils unless it has proven to have failed.
Side note: Because one coil is presumed failed does not mean the other 7 are going to go. You'll read on the forums of many many people indicating their vehicle is still running perfect with 20 year old original coils.
You can go with new coils if you'd like but should confirm a single coil has failed. At that point, based on what I have read on the forum, stick to Motorcraft coils. There are a few new account threads start with "I just replaced all my coils with Brand X and now I have a misfire. Anybody have any ideas?". Once they replace a misfire cylinder with the old Ford coil, their misfire has disappeared. Or the goal of user was to 'upgrade' the coils then experience a problem. Sadly, you can't return the coils that caused a problem so user spends money and a name brand product that was no better than the 8 year old OE part.

You never mentioned having a misfire.
You simply asked in this thread if the parts you listed were good.

To put the 'assumptions' into context.
About a month ago a user started an account to ask what coils are a good upgraded coil to increase performance on a brand new 2021.

If you are chasing down a misfire, swap coils between cylinders, a known good cylinder and the code-related bad cylinder. If the code follows the coil then the coil is bad. If you the code sticks with cylinder #5 after you do the coil position swap then it is not a coil problem.
it could be the plug you installed. If easy enough, swap the plug to another hole too. Then if the code follows, you know either the plug or coil is bad. Move the coil back and again check for codes, either the code followed the coil or stated with the plug.
