As far as being 100% positive on what would void your warranty:
Internal work (changing internal components)
Head work (new cams n shiet)
Transmission work
Modified exhausts (like rewelding certain parts, etc)
As far as the other kinds, like certain kinds of intakes will void the warranty, I've heard.
