Has any one had any warranty issues after installing CAI and Cat-Back Borla’s?:4-dontknow:

any modification to the engine, transmission, exhaust, or fuel system will immidiatley viod your warrenty. the thing is the warrenty says if it leads to repairs on the vehicle. dealers try to think you are stupid and say they cant repair the vehicle because they immidiatly see it or the computer comes up with codes saying that the mods are the problem. they have to do it the old school way and actually figure out what is really causing the problem before they say they cant fix it or charge you. i already ran into this problem so they just refuse to even look at my car cause they can do that until u get a memo signed from higher in the mail or some alternative. they made the mistake and printing out the warrenty for me to prove me wrong but they screwed themselves and were forced to find out my plug wire was bad because it touched my headers and melting a little cause misfires.

Thanks…I kind of figured as much. I agree that it would probable be more hassle then it’s worth for the dealer to try to get out of some petty repair. All I’ve done to my G8 is the Borla cat back and the K&N air filter. Hopefully I won’t have a bunch of problems with my dealer. Thanks for the reply.

It's an urban myth that modifications to (at least) intake and exhaust, post CAT, will automatically VOID a warranty. Such mods are covered in the US by the Magnusson-Moss Act of 1975 which in part precludes "tie-in sales" or essentially requirements that only parts from original oem can be used. So your exhaust rusts out and you don't care to file a warranty claim for an oem replacement, nothing prevents you from purchasing and installing other than oem parts. Modify the exhaust ahead of the CAT and you may find yourself in a different situation, although even discovering of a tune by a dealer should not happen unless there has been a powertrain failure.

Couple of illustrations as I see them (but not any official ruling)
1. you replace the original torque convertor with a different brand
2. you install a (soon to be released) K&N CAI
3. you use Amsoil or Royal Purple - a. same viscosity as in manual, b. viscosity other than in manual
4. you use a Fram oil filter (shame on you, even oem is way better)
5. you install a different cam and/or lifters, high volume TBI, aftermarket tune (especially one deleting rpm and speed limits)

In 1, 2, 3a, and 4 you will have no issues, even if something breaks.
In 3b and 5 if something breaks in powertrain you may get a denial of coverage.

What'll actually "void" the warranty? Racing. And proof they have been cited (not verified) as using is boasting on forums. :old:
