Pulled spark plugs at 43k

[icegradner]

I've heard of folks leaving them in well in excess of 100K miles with no issues. Mine have always looked fine at 100K. PSA - There are lots of fake spark plugs on Amazon and eBay.

Yeah, I changed the Iridium plugs on my last car at 121k miles, not that I was having power issues at the time. The big thing that happens over time is that the gap changes, making it less efficient.

Ya. By one-ten-trillionth of a percent.

Forgot to mention people that the forums I was on before I bought my Mav, (Chev, Dodge, American made, said that coppers are the best plugs, never iridium’s. But times have changed since then, Engines in the 70’s-80’s were so much easier to work on, in my opinion. Now I just take it to the dealer and say ‘do you know what’s wrong? Fix it please, Thank-you’. (I have a good dealer and techs, lucky I guess.)

I haven't touched an exhaust system since they've went to stainless steel.
Back in the '80s my Taurus was the first one with the stainless steel exhaust system.

Ok so this is kinda where I may be able to help. Since I’ve been doing ecoboost stuff for a while at all levels of performance.
First huge difference with boosted engines and plugs compared to hybrid. The new plugs on NA can last very long. As for anything turbo charged 30-50k is about as long as you should go before degradation begins. Now keep in mind this may not show up as mpg or any issues until it does. Speak plus gap gets bigger and that can cause the spark to “blow” out at high boost levels. Hence why most performance plugs are gapped down to 26-28thou.
Good rule of thumbs is toss them into general maintenance. If it’s just a daily and you rarely or never see full boost. These will last 100k then swap them. If you find your pedal meets the floor more often change them at 50k.
Life will be good. The maverick has about as easy plug change as you can get. Did mine very early and went one step colder and gapped down to 26thou. That is the general consensus for ecoboosts of all kinds for long term performance and safety.

How does turbo boost wear out a spark plug faster? Does the ignition system increase the spark at higher boost levels?

Or is something else in play?

I’m not sure exactly. My thought is they don’t technically wear them out faster other than maybe a bit more heat. I think we notice the degradation more in boost. The more air and fuel you cram in under pressure the better the spark has to be to not be “blow” out.
so I think it shows more in the boosted stuff. Although the plugs work but making spark it may be enough for Na but not enough for good burn on more fuel and air under more pressure.

Hey how are you. I’m at about 90k changed my around 60k and just bought another set I have my truck tuned do you think I should still use your recommendation of .26 for a gap or are there any other suggestions? Thank you,

Is it a big chore to change plugs on a 24 Eco? I’m used to changing plugs on V-8s in 75-78 GMC Jimmy’s or same in Chev Blazers where you could crawl inside the engine bay to do it . 80 Camaro is easy also! Getting old, miss those days. 🫩

1st car -'65 Fury with a slant 6. Talk about room to work! And you could put 8 bodies in the truck. Don't ask.

Just because of the mileage, two months ago I changed the spark plugs in my wife's 2016 Ford Escape naturally aspirated 2.5 l with 80,000 miles on it.
I don't think they look too bad.
I expect the plugs in my Maverick hybrid to last at least 80,000 miles

Was the gap still pretty close to spec?

Before I install new plugs, I checked the gap even on pre-gap plugs. I had the tool handy and I checked them. They were little bit bigger but not much. Then again, I have no idea what the gap was when the Escape left the factory.
