Spark plug replacement

[Brahmajoe]

Ford owned Autolite from 1961-1973.
It’s currently owned by FRAM.

Your point?
Chrysler also used them.
Should we care they are used in Fords?
Maybe they are great plugs and that's why Ford has chosen Autolite to make the Motorcraft branded spark plugs?
I've use Autolite plugs - a few I know who race use 'em. Top fuel cars, for example, official plug of NASCAR and some say even GM racers have used them.

Skipping a brand/manufacturer just because Ford has them make spark plugs for their own use seems a bit.................
Besides, they are made to Ford's own specs and requirements when they get the Motorcraft stamped on them They aren't the same as off-the-shelf autolite plugs.

Oem plugs should be used on the jeep I believe the auto light are a different length and the spark distance is different.

>>I believe the auto light are a different length and the spark distance is different.<<
Of which of the hundreds of different plugs they make? Which number is wrong? Autolite, AC, Champion, NGK, Bosch and others make hundreds of different plugs for hundreds of makes and models and engines.
So which of the hundreds of autolite plugs isn't right?

You are suggesting that some autolite plug you saw didn't look the same, you can't use autolite - that's how it sounds.

Bosch, for example, makes an exact replacement. I've not checked to see if Autolite makes an exact replacement or not. If they do - why not use it?

If it's a different reach or heat range, then it's real simple - don't use it.
But you appear to have suggested to not use Autolite because ford uses them to make their Motorcraft brand. Maybe don't use xyz oil filter because they make Motorcraft oil filters.

You should look up based on fitment and specs, not brand, then of those that are deemed to be or found to be a fit, you choose the brand you want.
If you are THAT picky, then start with the brand you want and see if they make a replacement plug.

There's different core materials and construction, different ground electrode construction (these days, even the ground electrode is as important as the core or center), there's heat range, depth, reach, and more.
If I found an autolite that crossed exactly - I'd not be against it because of the brand.

If today Autolite doesn't make a replacement plug for the 2016 and later 3.6 - then it's really pretty simple - you CAN'T use them because they won't be correct.
The books for spark plugs are pages thick for each company that makes spark plugs. NGK and Bosch both make exact replacements. Maybe autolite does or doesn't.

I know - these days companies struggle so hard to meet the "rules" and get mpg and low EPA numbers and that will go 100,000 maintenance-free miles that it's not like you can use ANY spark plug in ANY engine made in the last few years - even the ground electrode is now a subject of study and metallurgy, but it doesn't mean no one else makes a good plug for your vehicle.

Sort of funny, really - there's a TSB out there for misfires on the 2021 and later 3.6.
And guess what causes the misfire? Spark plugs - brand new from the factory. So I guess even Champion has their issues now and then. 800 miles and needed new plugs due to a misfire.

Brah…relax the manic machanic lmaoo. Any Chrysler Jeep Dodge modern car is not supposed to use autolite. Point blank. Mic drop ?

HAHAHA - that's hilarious. Boasting victory - or is it the old hip hop thing - finished performing?
Who told you that? The internet experts on YT?

Man, the BS out there is crazy. ?
No wonder people get confused.

So who told you this - or did you dream it all up yourself?

What a joker. Now you are just being silly.

OK, great spark plug expert - are NGK 7751 or Bosch 96337 or Denso plugs ok, or have you decided those can't be used as well?

Autolite - XP5701 fits all Jeep 3.6 engines of recent years.

But we'll defer to your web certification that no one can possibly use autolite plugs nor should they ever because they aren't right.

Well the upshot to this argument is now I know which plugs I can get ?

A little research shows most major plug makers have direct replacements - iridium plugs, for these.
Reviews on the parts store sites and amazon show decent reviews and ratings. Including Autolite and NGK. I never really did any research on the Bosch because IMO, they've always been decent plugs - unless they haven't been able to match these for some reason.
Once a design comes out, it's not a secret of how it's made, etc. - anyone can easily duplicate it. The manufacturers release the requirements, the plug makers get to work. A manufacturer would be short-sighted to make an engine for which only THEY can possibly make spark plugs.
Champion is no better or worse than any other.

IMO - do your looking/research, find the exact match for the OEM plug, pick your favorite brand or base it on reviews.
Some prefer to stick what what's known and what the OEM manufacturer installs - in this case, Champion. Others see benefit to choosing something else.
There's no "god of spark plugs". You'll see every one of them either trashed out there, or someone claiming nothing else can work as well (pick your brand).

The spark plug thing is third only to oil and religion and with those two, it's almost a toss-up.
Go visit an AMC page and see how each brand is trashed so thoroughly you wonder how any engine possibly survived.

But again, my suggestion is do your homework, look up for your vehicle on sites like napaonline, oreillysauto and others, look at reviews, etc. and choose for yourself.
For comfort - it may direct you back to OEM/champion.

BTW - AC stands for Albert Champion............ yeah, the guy who started Champion plugs. He was booted from his own company.
Autolite has been around for a century, only in the 30s got into spark plugs and have been OEM in a lot of vehicles, including Chrysler, Packard and others. For a while Lodge plugs were the choice of the Royal British Air Force.
Yeah, I did a study years ago on the origins and history of spark plugs and have a small collection of antique plugs.

I had a set of e3 plugs in a Kk that i loved. Then when i stuck a set in my
Jku it would stall out unless i kept feathering the throttle haha

yea, I’ll probably just pay the dealer to do this one. The maintenance interval is 100,000 miles for plugs. Ill be there in the next couple months. Just easier to have the heated shop have at em’

Sure it does..is that what mopar recommends though? Mic ?

Very wise

There's a ton of research that's gone into spark plugs I've seen everything from flat ends to rounded electrodes to wire electrodes and more.
Electric charges peak at sharp edges, not rounded or flat surfaces. thus the shape of the electrodes. Iridium is also very resistant to wear - the erosion from the spark itself. It's said iin a typical modern engine iridium can handle 100,000-120,000 miles.
That may be so - but I doubt I'll be going that far with mine. Likely more like 80,000 miles. Over the course of the lift of the vehicle - you lose more than you gain by pushing the limits on spark plugs.

Don’t put stock in what he says, call any legit mopar mechanic, don’t take my word but the mechanics and I assure you he will laugh at autolite

Mic drop crap, pretty sure of yourself. As per the same rules with any other part, MOPAR can't say you must use their parts. If another plug matches - or in some cases, BEATS, the qualities of the originals, maybe you haven't followed - hooked on your old-fashioned Obama mic drop celebratory move.
