I will say, that a few years ago some fancy chromed oil filters came out for the Honda Goldwing Motorcycle. These resulted in major engine faiures and were NOT covered under warranty (I worked for the Honda M/C division at the time). Any faiure of the oil system or related parts with an aftermarket filter on the vehicle would certainly be reasons for denial. That said, oiling faiures are pretty few and far between..I do not use the Nissan filter.
