@Bikeman315 ....I am a bit confused ( not the first nor last time) when you say "What he says is true but a little harsh" - I agree. Then you say take what I say with a grain of salt. HUH? Respectfully to readers be careful what you read into dealer or aftermarket parts dealers statements about modifications. I have too many stories of claim denials to list them but here's some food for thought.

Ford has some TV and youtube adds where they use their drift brakes etc. to smoke their tires in clouds of smoke or they rip around city streets at night smoking tires. Great.

At a meet and greet at a big Ford dealership that specializes in Mustangs, where an area Fred representative was asked to answer questions I was told one answer he gave made some of the guys snap to attention. When referencing the Ford official promotional ads and videos of Mustangs doing smoking donuts and brake drifts he said of course we don't expect you to actually do that. You could damage your car doing that. What?

There is a law suit going on now where Hyundai is allegedly refusing to honor a failed engine of a vehicle sold with a (very expensive) track package. The owner said on a TV news interview that he had followed all recommendations, that his vehicle had only been "tracked" at a track - not with the infamous street takeover crowd and offered his ECM downloads to prove his shift patterns and rpms were within approved limits. So far it looks like Hyundai will not honor his warranty and will not have to.

Regardless of what many believe to be tolerated, regarding modifications, you should read the fine print. That ought to give you some reflection time. ANY time you modify your Mustang outside of what Ford Corporate will approve (for God's sake ask them first) your are warranty gambling.

As for the dealer their word on modifications doesn't mean $hit - if they say Ford will pay for it ( no dealer speaks for Ford Corporate) and I bet if Ford won't pay for it the dealership won't either. There are several interesting videos of Mustang owners who had expensive mods done n- by ford dealers that failed subsequent warranty claims.

If someone wants to argue with this fine, it's a democracy, but I'm just trying to be helpful. I have modified and raced motorcycles, boats and cars and wrenched/built too many engines to count. I have always understood that I burned any warranty when modifying. Protect yourself - want to install some aftermarket headers - take 5 minutes and call Ford Customer Service ..... it could save you thousands.

There is no argument and I find your threads very informative. But if everyone called Ford before making a modification there would be no longer even be a Mustang. Mustangs are made to be modified and the enormous aftermarket is proof of that. Look at the Camaro and Challenger. Their aftermarket as a fraction of the Mustang and they are history. Now, of course, that's not the only reason but it is an important one.

Now as far as Ford, or any manufacturer for that matter, their warranties are written in invisible ink. Most of the time there is so much room in between the lines that a Mack truck could drive through them. They constantly move the goalposts and what is good today is bad tomorrow. Calling them is pointless. I wouldn't trust anything any one of them would say. I would feel far more comfortable trusting my dealer whom I have an excellent relationship with.

Regardless, modifications are a crapshoot. As you pointed out the moderate ones will not raise an eyebrow, nor should they. Major ones, especially to the drivetrain, can be a cause for concern if your warranty is important to you. In OP's case the filters are the former, the carbon traps, if found, could be the latter.

The carbon traps affect nothing but emissions. You wouldn't get a warranty denial from removing them.

 

[MAT1955]

@robvas ..... actually I disagree. You have not only altered the emissions (illegal in many jurisdictions) which are linked to engine performance you have also altered air flow into the engine both of which your dealer or Ford could easily use to deny a warranty claim.

@DrRaphael ..... if you still have any patience left with my long posts - you may find the following interesting ...... I have posted this before, but when I purchased my 2024 GT I wanted too install a wired-in (analogue) kill switch. As that could void engine warranty because it would involve splicing a kill switch into an engine electrical operations system - like the fuel pump, I wanted to be sure not to void my engine warranty. A local Dodge dealer has been installing kill switches on their high performance cars for years. So I telephoned Ford Customer Service. They were AWESOME!!!!! I got right through to a rep. She was real smart. She wanted to know the exact details. She said she'd call me back. She did in about 10 minutes asking me which Ford dealer I wanted to do the job. I selected a Ford dealership about an hour away that is known as Mustang performance specialists. She took the name of the Ford dealer and said she'd call me back. She did about 30 minutes later with a specific approval IF I had the work done as specified and IF it was done by that exact dealer who I named. She gave me a case number and said it was filed on my account. Soooo for a few minutes work I have a Ford Corporate approval and the approval of the Ford dealer in question. Confirming a mod with Ford was easy for me to do and gave me the peace of mind as that Ford drive train warranty is a pretty lengthy one that I would not want to void. I have not installed the kill switch yet but may once the car comes out of hibernation. BTW if she had said no, obviously I would not have done it and instead just pulled the fuse for the fuel pump if leaving it in a hotel parking lot overnight - which I have already done a couple of times while parking in sketchy parking overnight in 2024. cheers, MT

Mat1955, I'm not tired of your posts; any helpful information is welcome.

Well the great news is it’s a coyote engine and you have next to zero likelihood of any warranty problems with your engine.

If I were you I’d slap headers and a blower on it, change the plaque to 850 and get on living life with a worry free 850 HP

These engines are very robust and stout!

@robvas ..... actually I disagree. You have not only altered the emissions (illegal in many jurisdictions) which are linked to engine performance you have also altered air flow into the engine both of which your dealer or Ford could easily use to deny a warranty claim.

That is incorrect. I worked for both Ford and a Ford dealership. Without a direct case to refer to, you would require need progressive damage. If an engine has an exhaust leak, was the carbon trap involved? No. If an engine has a valve drop, was the Carbon trap involved? No. It has to be in direct correlation to the failure. Carbon traps being removed will only be denied for warranty in the case of you having a warranty around the assembly (intake tube) they are in. Most likely because you have damaged the structure taking it out and by cutting the parts that hold it in.

Also to your post above this one on dealer warranty. The dealer can file to have their warranty rate increased annually. State laws dictate this. In the state of Texas (and a some others) you submit 100 consecutive ROs and they will adjust your labor rate to this. Same for the parts markup. The dealer also doesn’t deny your warranty. They decline to work on it. What drives this is the Ford dealership environment is measured on specific warranty sections such as “drivability repairs” and then measured against other groups of like size and proximity. This drives some dealerships to avoid warranty work not because of the actual repair but their metrics with Ford. The outcome if they get too out of line is an audit and the audits can be rough. This typically results in some sort of chargeback from Ford for any repairs that they don’t have the old parts, good records, etc.. I’ve seen a perfect audit and I have seen one resulting in a 400K chargeback.

You can get denied from one dealer and go down the street just to have no issues and get it approved.

A dealer can place a warranty cancellation on a component or an entire assy. Example: if you tried to say the engine failed and you have 55K on the odometer. They inspect the vehicle and it is found to have extreme sludge and the original oil filter is still on the car, they document this and submit it. This is in rare and I mean very rare and in extreme situations. You can still appeal it with a Ford Zone manager (may have a new title now) or a Ford service engineer. Just ask the dealer to do so.

Edited for grammar and clarity.

So, are you saying that if the carbon traps were removed, they may have cut/damaged the intake tubes to do so? If they were removed, can new OEM parts be purchased and reinstalled?

Here's how they are removed:



Unless you're in California or another state that that's going to check shit to that level I would just forget about it.

I highly recommend getting on YouTube and searching for 2024 Mustang carbon traps. The videos will show you exactly what folks are doing. Some pull them out clean. Others who do not care, tear them out. And yes, everything is replaceable. If in fact they are not there, Carmax has to replace them as it is part of your car’s emissions system.

 

[decidave8]

Ya some people cut out the plastic retaining structure that holds the carbon traps in place. no need to but I have seen people do it that way. you could order them from ford and put them back, granted it seems like it would be a pain in the ass to feed them back though the plastic holding them in.

Yup. I just got back from Carmax, and the previous owner cut them out. Carmax is replacing the air intakes next week.

Thanks. I watched that video and others last week.

According to that video title up there, you gonna lose 20 HP (I still have my carbon traps in).
