Plugs/coilpack replacement.
Have a 17 6.2 F250 with 117k on it. Bought it with 50k, has been good to me (knock on wood). Not giving me any issues but I've noticed it's gotten a little sluggish over time so figured it's time for some regular maintenance. I know these have 2 plugs per cylinder and a standard number of coils. Anyone done this job yet? Have found vids on YouTube on the previous generations of the job but none of the current models. And any advice on plugs or coils? I've generally went with motorcraft products but I see all these gimmicky claims from plug manufacturers.

X2. Stick with Motorcraft. My father-in-law swapped to the Accel coil packs on his 5.4L and had to replace two because they cracked some how. He didn't notice any increase in power or mpg as they claim.

My friend I did the plugs and wires on my 2011 6.2 L at about 100k miles. It wasn’t a bad job. I took the wheels and inner fender shields off for access to the lower plugs but you probably don’t have to. I’m guessing it’s probably about the same on the newer models. I used original Motorcraft parts from amazon. I was actually very surprised how well the original plugs held up.

start with plugs first. you should notice the motor feels more responsive / crisper with new plugs ( every 100k ) ...maybe a K&N air filter...coils packs may help but probably not necessary at this time.

i dont know who is making motorcraft parts but denso is the leading authority on electric stuff. theres a reason why you see toyota alternator, fuel pump and coil packs last the life of the vehicle. replacing coils at 100k would be disappointing if you ask me
