Which Mods do/don't void warranty?

I'm getting jealous seeing all you guys/gals mod your Stangs and I was wondering...
Which types will not void the warranty and which will?
I'd like to change to larger wheels and add some speed, preferrably without breaking the bank.

any mods that doesn't alter the basic functioning of the engine will not void your warranty, see magnussen moss act or go to SEMA.org.

Pulleys, CAI, exhaust, etc, will not void your warranty, but the new parts, themselves, of course will not be covered.

N2O, SC, Turbo, and chips will void your warranty, as can racing of any kind.

Hey, thanks for the quick response! But can you repeat that for those of us who are not motorheads? :dunce:

What does CAI stand for? What difference will pulleys make? What's SC?

I'm not looking to impress other gear-heads with 1.5% more horsepower on the dyno, I just wanna feel like I'm going faster and leave more dust then I do now in my V6.

How can Ford tell if you've been racing? What if I always drive like I'm racing?

:winks

Thanks,

Thanks,
The computer tells on you. OBDII computers monitor your driving for download.

CAI = cold air intake

pulleys = underdrive pulleys, slow rotation of accessories like AC, alternator, etc, making engine more efficient (generally good for 10+ hp and 1-2 mpg)

SC = supercharger

you can also change your gearing without voiding warranty . ..
Warranty and Mods

We sell the Saleen and Roush
Any option that is placed on those vehicles is warranteed for the full 36/36 except NO2
Any option that YOU might put on your car is warranteed by the company doing the mod or the mod's company...if it needs to be removed the REMOVAL is not covered by the factory warranty, however if the part is a Saleen or Roush part, installed by Saleen or Roush or a Roush or Saleen dealer, it's covered. They call it a 'transparent' warranty.

If the dealer can't, in writing, tell you that the part installed caused the failing of the FMC part, it's got to be covered. See the Laws on SEMA...if you have any other questions

I had a question on that too... If one grenaded the bottom end with a S/C by the above brands is it under warranty? Howabout if I do it with a Vortech or Paxton? My MX mgr said that he'll fix anything once... just wondering if that's true in all or at least most cases...??

I know if it's not proven related to the mod Ford is liable (Moss) but to take +500 outa a 300 HP car could be related to allot of things (engine of course but also drive train, A/C and generator (if you move the rev limitor), brakes, etc...)

Thanks in advance for any insight!
Check With Dealer. They Will Tell You If The Mod Will Be Covered Under The Warranty. Most Mods Are Covered With The Exception Of Nos (nitrous Oxide Systems) As Long As Ford Installs The Mod For You.

Yes it's covered under warranty if it was installed by an authorized dealer in the above brands or it came on the car from Saleen or Roush. I don't have a clue as to what Paxton or anyone else will or won't do, so I can't comment. 'Proven' isn't exactly correct. If a DEALER says the part failed because of "X" part, and THEY PUT IT IN WRITING, then it's either the problem of the part manufacturer, the dealer who installed it, or it's up to the customer to take Ford, the dealer or the manufacturer to court. Paper words are easy, enforcement is sometimes hard.
Thanks gentlemen, I too was wondering about the warranty question. Does this extend to the dealer sold extended warranties as well? I'm considering CAI, headers and dual exhausts, along with some suspension mods. Would you agree the best way to go from a warranty standpoint is with the Saleen or Roush parts installed by the dealer?

the mods that break your car usually void the warranty...

LOL, I'm affraid you're RIGHT ON!!

PS. Your sig is too long, sorry to be a stickler... :rolleyes: Pls. fix it... :worship
Also don’t forget about common computer limits. Our on board computers do not have the capacity to store days and days of information in them. I was once told that they can really only record the last few minutes of driving (for crash needs) and then of course just store obd2 codes.



And yes from my own experience, the dealer does in fact have to prove that your part caused their part to break. For example we can take one red 99 Ford Ranger 4x4 with the 3.0l flex fuel engine, off road pipes, upsized tires, nerf bars, damn nice looking, traded in for a 05 mustang gt…(sigh that was a fun truck, can’t really off road in the stang)… anyways sorry to wonder off there, but the truck in question had a problem with BAD knocking on heavy acceleration. Well I had, err the owner had made his own “CAI” for it. Well the dealer tired to tell them that was the problem and it was doing it because of way to much air coming in to the intake………Well, problem is they tried to pull that one over on a ex-ford mechanic that knew his EGR valve was bad due the solenoid not moving right. Anyways I made them prove it to me and they could not, had them check the EGR and they replaced it. Damn it felt good to be right at least once in my life.

Zman2800, I'm a bit off topic here, but that's good to know. I had considered that I could use this info to fight speeding tickets. About a year ago I got one for 88 in a 75. I told the cop I would buy 78, but not 88. Luckily he didn't make me turn the car off so the cruise control was still set. I also had a GPS system and digital camera with me, so I was able to reengage cruise and record the speed along with shots of the speedometer. I presented all this to the judge and he agreed there was reasonable doubt and dismissed the charge. The onboard computer data would have been even better since the ability to tamper with it is much more limited.

If you wanna keep that as and always possibility get something like that little carchip device they sell at autozone and some other places.

300 hours of data is a verrryyy long trip. I have also seen other data loggers out there that do the same. I don't know if this one timestamps stuff, but i swear that I have seen some that do.
