SPARK PLUG ISSUE RESOLVED | Ford 7.3 liter GODZILLA V8

- On a recent camping trip, we experienced a SERIOUS issue with the WreckTech Shop Truck, and want to share how we solved it.
This solution works on ANY 2020 Ford Super-duty with the 7.3 Godzilla engine, and possibly more applications with the same engine setup.
The Autozone guy is likely still telling the tale of the guy that wanted spark plug wires for his 7.3 diesel...
On the cylinder numbering, right and left are from the inside of the cab looking out, so the left bank (driver's side) is actually bank 2- # 5, 6, 7, & 8. The right side (passenger) is 1, 2, 3, & 4.
So true, first he said 2 was on the left then on the right. I had to look up the cylinders to find the right side
So where is #2? I have 11 of these motors and now I'm getting these misfires #2!!!!!!
Makes me love my old chevy 5.7 vortec
I have a 2020 Silverado 3500 dually with the 6.6 gas 42k miles no issues so far. Tow 18k gooseneck regularly.
There are three different part numbers for the 7.3L spark plug wires. The "C" version is the one they are putting on F53 RV chassis now, and the heavy duty trucks. I have a set on mine, and so far they are working just fine. I've tried two different types of aftermarket ones so far, and they have both been garbage.
Great info, thanks!
I picked up a set of wires for an LS engine off Amazon so far no issues
Ford Part # LC3Z-12286-C
It is a well known issue. CZcams video have covered it for a couple years. At least one channel claimed that Ford has since redesigned and resolved the part.
Honestly, Ford should issue a recall (if they haven't already done so) for all the 7.3 engines using the earlier, and apparently defective part.
Issue is while they have a revised version they refuse to install it in the trucks so every truck that rolls off the line still gets the same shitty wires, you have to buy the C series out of pocket.
@@SMiller5488 Really? Even in late 2022?
If I were in the market to replace my 2017 F-350 with a new one having the 7.3 engine, I would make it a condition for the sale that the problem plug wires be preemptively replaced. Other than purging old stock (that's still a poor excuse), WHY would Ford continue to put defective parts in? The Ford warranty includes roadside service. Even a small percentage of truck failing would cost more in tow services than any savings gained by installing lousy parts.
Ford should design a heat shield for the exhaust mani to help isolate heat and/or beef up the wires
The issue is trapped heat, they came out with a new plug the solves the issue although you have to buy it out of pocket as it only comes on the med chassis trucks
They did, just use the commercial plug wire for 7.3L Ford uses in their F650 - F750. Part # LC3Z-12286-C
I’m genuinely curious on when ford will issue a true fix for this, it’s crazy how common this is, that some people recommend to carry an extra like 2 on you at all times cause it makes it basically undrivable
Ford has a answer its called the C series wires and is the only correct fix

15K pound trailer? I have a 22 F250 7.3 3.55 and IIRC the max tow limit is 14K
On mine, the problem appears to have been a bad connection between the carbon conductor and the plug clip. The "wires" are not wire, they are carbon conductors. The bad connection allows the spark to burn away the carbon, farther and farther, until there is too much resistance to fire. A hollow section inside the insulator. The "C" wires should be the fix and cost about $12. each. Get a full set from someplace other than the dealer.
Why do you say not to get them from the dealer? Cost?
@@hossbronco My dealer "discounted" them to about $34. each and only had the original model, not the suffix B or suffix C. And that after telling me that I didn't need them because wires should last at least 100,000 miles. Pretty incompetent. Plus, they had to order them. Rockauto had the suffix C model wires for much less and I had them in a couple of days. Can't remember the price, but somewhere around $8-$11. So many guys have commented about them melting form the heat, but that's not the problem. It's also interesting that when one wire fails, the engine runs terribly, not just a miss on one cylinder. I think this is because when one cylinder stops firing, the engine pumps unburned fuel into the exhaust. The Ox sensor sends the info to the computer and the computer interprets it as too rich in general, so it leans the mixture to all cylinders to the point it can barely run.
Odd, mine misfired on cylinder 2 as well, but at 51k miles. Oreilly auto sells some nice aftermarket plug wires with more insulation than the original Ford parts.

I have a 2022 with 42700 miles and it just started this morning. It actually looks like exhaust gas is going straight through the plug, there is black soot inside the boot and on top of the plug itself.
Thanks for sharing bro. I keep a skan tool I'm the glove box. I'll just change them all now and avoid this.

I really like that truck combo and planning on a F250 with the 7.3. Weird to hear about that wire, no way a set of oem wires shouldn't last at least 50k minimum. At least it was a front cyl.
JV is a favorite here too for MCs and Jeep.
Honestly man, it’s a great truck! Sucks some gas 😅 but other than this issue it’s great!
@@MotorizedCo Just curious what you got towing that trailer mpg and what you get empty on highway speeds Thanks.
Easy fix man . This is common for 2020. Also major transmission recall. I purchased 2021 no issues.
Still the same issue on ever 22 that rolls off the line...
@@SMiller5488 none here in us . Dont know what dealer you work af ?
@@SMiller5488 2020 only was major recall , tail shaft of transmission. Absolutely no issues beyond recall
@@rontopping2048 lmao I know of tons of 22s that have trans replaced
@@SMiller5488 none here I work for largest Ford dealership in new England
Removing a spark plug wire and not connecting a spark plug to that wire can damage the coil as well as the wire when engine is started.
Coils need to be able to send that High Energy to ground or they can become damaged.
I mentioned this a year ago my Chevy co van the wires lasted 105 k. Aftermarket 70 k I'm on third set at 205.k
Cool!
@@MotorizedCo me,being 136 yr old, thats the first thing you look for,,spark,,then fuel.. get some heat wrap for them, or god forbid,,chev wires...uuuuugg,,i shiver...
Mine has random misfire code when I'm romping on it. Still haven't figured out why
I gapped the plugs to .30 and it went away.
Isn’t it amazing how this shit always happens at the worst times ? Always !
It seems to be the way it goes!
Exactly, never happens as you drive by a dealer that just so happens to have 50 of them in stock and techs waiting around to help you free of charge. 🤷
something I've noticed is that chevy trucks usually have a heat shield over the exhaust manifold and fords never do....chevy trucks always seem to run quiter longer before they get manifld leaks....I have heard many many fords only a few years old with exhaust leaks vs many quiet cheverolets that are 10 years old or more still nice and quiet.....it is not my biggest complaint with ford but damn it is about time they make some improvements in this area
If I'm wrong tell me why
Late to the party since they came out the wires go bad easy fix and cheap 😌
So basically a modern day 5.4 Triton 😂
Not even related.....try again.
That engine is more closely related with an LS than a Triton . 6 bolt main skirted block .....
@@Dr.Westside
The modular Fords also have deep skirt cross bolted mains....the Ford FE had deep skirt blocks with the 427 having cross bolted mains.
It's not an LS thing....but it is always a dumb thing to claim other motors copied other motors...INCLUDING the morons that say the LS head is a copy of a Windsor head.
That's the left side not the right side.
Ridiculous to have plug wires in 2022
Oh, that’s right, your electric truck doesn’t have them.. 😂😂
April 2023. Truck started misfiring. Replaced all the spark plugs.
July 2023. Truck started misfiring again, having to replace Spark Plug Replacement: Replace spark plugs, one ignition coil and ignition wire 😡
You got a lot more problems than a sparkplug on that thangg lol
Drivers side is the right side?
Driver side is generally considered as the LH side of the vehicle.
Cylinders on the 7.3L start at the passenger front.... 1 through 4 working your way back. 5-8 are on the driver's side, starting counting from the front working your way back.
Thank you for clarifying, I may have misspoke here!
Better than Ls swapping a ford lol
Blasphemy! Love your content, keep it up!
Probably the best thing you could do. If someone makes a LS to big block c6 adapter I would be on it.
Only Ford would run a wire right next to the exhaust and not put a heat shield there. They seem to have a "it'll be alright" attitude.

When will Ford get one thing right??
As if GM or Dodge are any better 😂😂😂. They’re all overpriced garbage.
It's no longer a Ford if Chevy had to fix it lol 😆 6.2 liter vortex or 5.3 liter great engine's 👍or the duramax diesel with military grade Allison Trans
What's a Vortex???
