Anyone have a clue as to what popular mods will void the factory warranty?

I am about to add a JWT and Z-Tube, TEIN H.tech springs and maybe a set of Crawford cats with a Plenum.

Will any of these kill my warranty?

Unless they can trace your mods to your problem, you're safe-- some dealerships dont care, some are amazingly strict-- when all else fails lie. Just take it out and put in stock w/e you replaced.
