I assume you mean "ruining" the engine ;).
I spoke with the dealer and told them I would be putting a secondary filter/water alarm system. They didn't say it would void anything or not, and so at this point, I don't really care if it does. I'll have better piece of mind with it there.
Having said that, to anyone else, I would advise seeking written advice from them, and probably have them fit the unit themselves.
