I cant remember if I replaced it or not. Its either the stock one that was on the car when I bought it, or I replaced it when I did my radiator. I cant remember if I replaced it or not. If I did replace it then its actually from another car, I didnt get original nissan hoses because the lower rad hose is stainless steel tubing so it wont collapse, so I didnt want to pay $$$ when I was cutting them up anyway. I have a feeling though it was the same one that came with the car.
