If they say that it will void any warranty, they can and have been successfully sued. It's garbage what they're saying. Part of the reason is that ALL car manufacturers DON'T make their own filters. Aftermarket companies do. And to say that not using OEM filters voids a warranty is like saying that there is no filters made that will. (Part of the ruling from the courts.)

I suggest you go elsewhere. They're telling you a lie (and they should know it).
