I have an 08 5.4 SCREW is there any reason to replace all 8 coils? I've replaced 2 that had gone bad but is there any reason to replace all 6 due to mileage? Truck runs well just idles a little bit rough

They should be good to 100K ...then replace them

Is there coil over packs better than others?

Driving around running errands my truck started missing like crazy, pulled engine coded off my evolution and said it was my number 5 coil. Wasn't around any dealerships but pulled over and ran into a advance auto and picked up a accel replacement for $45. Very well made and popped it in in the parking lot and haven't had any issues yet. If you can't afford the motorcrafts then I would recommend the accel.

I found this the other day looking to buy all 8 and it sold me on those accels

Im looking at Duralast from Autozone. A buddy just bought eight for $300 and they have a lifetime warranty. I cant find motorcraft for under $350 and they only have a 1yr warranty. Those duralast seemed nice when I installed them for him. And Autozone is good about honoring warranties.

So if I'm at 100k my truck will really run better with a new set of coils? It's not missing or anything

I'd say so, gonna need them soon enough, I did at 118k, I bought the acells off amazon for $200, and use some dielectric grease to put them on
