Ecoboost spark plug interval

[buck91]

How often is it recommended to charge plugs in the newer ecoboost engines? Specifically my 2018 F-50 2.7L. No drivability issues and mileage is normal so I’m not sure if it’s needed but with almost 60k on a turbo charged motor wondering if it would be good PM.

If no code or driveability issues then it may be best to follow mfgr recommendations on change interval. If you do decide to change them make sure you do it with engine in cold state and use anti-seize on the plug threads. Seeing a lot of people skip the anti-seize and paying for it dearly later in the vehicles life.

You don’t want to use antiseize.

At 75K miles our 3.5 EB developed a cold-idle miss that was cured with new spark plugs. The old plugs were just outside the spec. for gap.

Seeing a lot of people using antiseize and paying for it dearly later in the vehicles life. Same can be said about not using a torque wrench.

60k miles severe service
100k miles normal service

Obviously depends on fuel quality and driver habits...

Invest in a quality torque wrench and work on a cold engine.

How difficult is the job?

why no antiseize on these?

You don't use antiseize on just about any modern plug, they're coated in a way that the threads should not seize, and anti-seize increases the risk of over torquing and stripping fragile aluminum heads. The only place where I'd use anti seize with modern-ish plugs is on the portion below the tapered seat on those awful Ford 3v modular engine plugs.

Change them.

Easy just take tour time. there are you tube videos.

My cousin had an indy shop in town change the plugs in his wife's 2017 NAVI @ 80K miles. It too developed a miss. New Motorcraft plugs fixed it.

I usually do mine around 70k.

Pretty easy job on the 2.7. Only one that had an obstruction that made it a little harder.

I did them on my 2016 f150 2.7 at around 61k miles. Plugs came out looking really good, and the gaps were not far off from spec. No change in fuel mileage or anything else after changing.

Decided at the time that with rampant posts about all ecoboosts being hard on plugs to follow the severe schedule. Based on what I saw, I may go longer nextime. Been over 30k miles since I changed them.

Electricity always takes the easiest return path.

60k is my limit on stock forced induction engines. Being how finicky they can be on gap, I'd rather change them early than late. I know some folks who will pull the plugs every 20k and check the gap, but that's mainly the tuned guys.

I pulled the plugs on my 3.5 EcoBoost right at 60k. They looked good but their gap was just a little more than stock specs. New Motorcraft went in.

Make sure they're the correct gap when you change them.

Just put some Bosch plugs in a coyote with iridium on the tips (0.6mm fine wire) as well as on the ground strap. See plenty with platinum grounds but never noticed any with iridium. Wonder how much of a longevity or any other difference they will make.

Without anti-seize (which is cheap insurance) on aluminum heads, you can run the risk of never being able to get the plugs out again. It is not any fun to break off a spark plug in the head, and then have to pull the head to do the required fix. 3V Triton engine Fords are famous for seized and or broken plugs.

I miss understood your post , I am an antiseize user since the 1970'aluminumm heads and almost any thing I know I want to ease repairs on.

Many companies specifically say DON'T use anti-seize. https://ngksparkplugs.com/en/resour...hanges the,unnecessary and can be detrimental.
