I have a 2014 limited v8. Just turned 100k miles. Preparing for full tune up. What are the best plugs? Was thinking Accel ignition coils while I'm in there. I have a KandN air filter already. What else should I be looking at? Radiator flush? Trans fluid flush?
100k tuneup time

Skip the coils they aren’t a wear item and just fail, old oem is more reliable than A/M. Best thing to do is buy one spare Ford cop and keep it on the truck. MotorCraft plugs are the way to go but NGK are good too. Avoid champion imo, they used to be decent but I’ve had issues with them in the boat and lawn mower.

Chuck the k&n in the garbage, you should have done Mtrcrft plugs and flushes long ago, coils are fine, don't fix it if it ain't broke.
2014EL 5.4. I did plugs at 75K, Motorcraft. Will do again at 150K. Agree with ^^ on COPS. Defund the COPS (just a joke, sorry). Also did snake belt and coolant at 100K. Will do front & rear diff, transfer case, and tranny fluids as soon as I start doing long distance drives again (now @102K). Nice to do a lot of the scheduled maint at 75% just for overkill and peace of mind.

+1 on skipping the COPs and Motorcraft plugs. I've never used NGK plugs on my trucks, but I'm with that suggestion also if you prefer as they make fantastic plugs (have used them in all of my wife's cars). Do the trans and coolant for sure.
You OK? Worried about you.

Only replaced one plug and coil pack out of the original eight when I got a misfire code. Still running great after 16 years and 268,000 miles.

If this will be your first time tinkering with the tranny, then make sure you have the following tools handy:
^^^ the OTC 307-570, and:
^^^ an Irwin long reach offset pliers.
If you're good with tools, the above two units will enable you to work on a 6R tranny all day long without having your skin burned off by the cat.
Also, be very careful as to how you "flush" the tranny. The 6R80 is not very forgiving when you run the pump dry for any period of time. I, in my flawed opinion, suggest that you drop the pan, do the filter, then fill up as it's normally done, then come back after a weeks worth of driving and replace 5qts of tranny fluid out the dipstick hole.

If you wait 100K to, 'do maintenance', then post a question on what 'What should I do'. If you gave a rip you realize doing maintenance, is kind of important. You obvious read the 100K spark plug interval. Why wait until it actually turns 100k? That is maximum recommendation. The owners manual should have this info. I wouldn't trust the opinions of half the people on this forum. It's sounds like you want permission, to delay doing anything else.
I dont recall ever saying I've never done any maintenance to this truck? Also I bought it used about 30k ago. Its had plenty of maintenance from both me and the previous owner. All I was looking for was a recommendation on plugs really. Simple. Im thick skinned and can take a poke all in good fun, so im really not bothered by your snarky response. There is a lot of ego on these forums for whatever reason. Im an old car guy...just simply asking for a recommendation on a newer vehicle that i am admittedly unexperienced with.. thats all...Motorcraft plugs it is...ill keep my stock coils. Cheers

Damn! I never thought of using a pliers to pull that dipstick! No more scars on this hand! You saved my skin, for which I will be eternally grateful!

Makuloco has a way to do it simi cold, I think I will do that on this new to me truck or maybe just throw towel over the cat.
I just bought a 14 Limited with 98k miles and immediately changed the oil (never trust the dealers to do it right), the plugs with motorcrafts, the serpentine belt and tensioner (it was making a bit of noise). Will probably drain and flush the coolant this weekend and do the trans at some point.

I did my plugs at 60K, nothing wrong just needed to do something,( all plugs looked good).
NGK IX Iridium Spark Plug 372
Have Flowmaster cold air induction
I replaced all four struts, rear diff serviced, all 4 brakes, (lifetime guarantee and flushed system), replaced leaking pwr steering hose and flushed sys at 75K, tires rotated and bal. It drives like a new vehicle, runs sweet!
I just did the trans and radiator flush at 80K
This is the last V8 and it's going to run until the doors fall off!
