Like Hambone said they are wrong and they are right.
If you change intakes, and exhaust the computer will adjust for the different volumes and readjust their tables.
Now if there was a failure due to the new parts....let's say that the catalytic converters fail for instance, they can say that with the new parts on that it caused the failure and not cover it...that is true.
While the converter has an 8 year 80,000 mile warranty, they do tend to see if something is modified and give you heartburn for it. Just is!
