2005 Mustang Mods that DON'T void Warranty

That actually WILL void your warranty when you bring her in for burned pistons.

I put dash inserts on mine, that should be warranty-friendly :D

I'm just curious on how higher octane gas will cause burnt pistons.

As I understand it the higher the octane the harder it is to burn (less combustable).

As for mods I would see how your dealer reacts to mods before doing anything serious like S/C, Nitrious, etc.
Such things as, rims, cold air intake and catback ussually dont raise to much of a hassle from most dealers and will only void the warrenty on the parts your replacings but it could also void any asociated parts attached to them.(cause - Effect)

The dealer (if they are a real dick) might say nice rims but if your wheel brgs go they might say the aftermarket rims caused it.
Just remember if they can get out of something they will even if they are in the wrong.
It's up to you to sue them if the dealer and Ford does nothing for you.
 
Dunno if this helps but I was talking a little with the dealer when I picked mine up and he was saying anything with the computer mods (if they catch you) will void the warrenty. He said exhaust mods shouldn't though. Anyway, if something does go wrong the burden of proof is on them to show that your mod caused the damage.

This is true, but the dealer can make your life living hell and you are going to be out a car for a while. I know it happened to me and I didnt win.

The best possible advise is one of 2 things.
1st with any high HP mods like nitrious and S/C be prepaired to pay if you play
2nd with any mod if you do break anything put it back to stock. Never let the dealer know what you got.

BTW, the 2nd thing is very dishonest but if you can live with it so can I. :)
 
MAGNUSON-MOSS WARRANTY ACT -- Public Law 93-637 - 15 U.S.C.

Unfortunatley, the way that the Ford 3-36 Product Warranty and Service Contracts are written is that the changes made to the vehicle must meet the manufacturer specifications for replacement or OEM. So, if you make a modification that is not within the specs of the OEM and it causes a terminal failure, then the Mfg. has the right to exclude coverage under the warranty. However, if you make a modification and have relied on the manufacture of the after-market product, who has stated that the product is OEM compliant, then you may be able to work with the product supplier and the warranty service provider to make the repairs under warranty.

Here is a link to the Center of Auto Safety that gives a fairly nice brief on the law.

Other than apperance changes, I have always waited until the warrenty expires and then live by the "You play - You pay" law of life... :)

Ford and Chevrolet have been trying to find a way to curtail covert warrenty fixes for years, and I think with the advent of the Flash & Retune, they may just have it! DAMN IT! :nonono:

Good Luck...

Higher octane burns slower but hotter than a lower octane rating. Going from 87 to 89 is no big deal, just as from 91 to 93; but I would not make the jump from 87 to 93 without a flash/tune. Your AF ratio will be off since the computer was set from the factory to use 87, my dealer told me that running 93 would void the engine's warranty. But in the same conversation they offered me a chip flasher, so go figure.

BTW, my 97 Cobra ran like arse on 91 octane...it did NEED the 93.
 
Bill is very proud of the Mustang, so proud in fact that he does have his favorite car in the world bone stock. So yeah, keep it stock for the warranty period, then the standard rule of you play you pay applies.

Just be careful. That warranty act has more than one part, and it is that other part, the part most aftermarket part places forget to mention, is what can get you.

That warranty act allows manufacturers to completely void the warranty if there is any sign of abuse. "Racing" (in any form) is considered abuse. If you make high-performance mods to your vehicle, especially if you make several, those mods can be considered evidence of abuse. Basically, the theory is why would you have made those mods if you weren't making use of them?

However, as noted, a lot of this is subjective. If you have a "good" dealer, then you will not have a problem. If you have a "bad" dealer, he/she can make it a living hell for you.

This has been covered before but...

Higher octane gas requires more pressure (or hotter temperatures) to ignite. It does NOT make your car run hotter and it will not change the A/F ratio significantly on a stock tune. It allows you to run hotter (or more compression) without pre-detonation. A 93 tune will generally run more spark advance which will require a richer A/F ratio.
