    Yeah, got it done. Rather have the peace of mind knowing the coils are in good shape. Gotta say, hardest part for me was getting plug wires on firmly on the lower plugs. I’ve got some small fingers, but hard to tell if they are on all the way or not.
    Truck runs great now.

    All the tips in here are great. The wobbly spark plug sockets are clutch!

    Lost one of the black spacers that the coil boot screw goes through. No biggie, but could it possibly drop in the spark plug hole with the plug out?

    Found the spacer, used the NGK 6510 gapped.030 bought the tool from Amazon that was posted on here. Best $20 I have spent in a long time. Made the job so much easier. Thanks for the tips on here really, really helpful!!

    I'm reading through all these tips and tricks and DIY threads on tune ups and in looking at the wires on mine, motorcraft 8mm, they don't look very old at all. I will have to pull a plug or two, top and bottom and see how they look. Could I catch a break on this one?

    My tops weren't bad but easy enough to change them.

    Disclaimer: I haven’t read through this thread nor researched it on my own.

    Is the second set of 8 plugs an emissions item or do they both fire at the same time?


    I think I remember my 2006 5.7 HEMI had 16 plugs as well but only one set was necessary for ignition and the second set somehow contributed to some emissions reduction.

    I will change our all 16 when I do it, just curious.
