Electric fan mod...I remember doing that onmy rx7, lol. Shipping a motor won't always void the warranty, but depending on the dealership(personal experience), be ready for a fight of fault. A lot if theae aftermarket chips are also removable w/o detection and simply plug and play if programmed from manufacturer. I'm looking into a chip for my tundra where it'll be programmed for volant intake and exhaust from the maker.
