After asking the dealership to put this in writing they quickly backed down since the Nissan Oil Cooler is considered a nismo competition part and does not come with any type of warranty from Nissan. The dealer will only point towards you warranty manual which is vague on the issue. I also checked around with other dealerships with the same response. Dealers say that by putting on an oil cooler will not affect you warranty unless the oil cooler fails and causes the damage. (Which from a legal standpoint I understand that this is the case) From several talks with consumer affairs, by placing an oil cooler on the vehicle that they classify as a competition part that the car has been modified for competition use therefore having the potential to void your power train warranty however the did say that your radio would still be covered.
