Pretty much anything you find outside of genuine Nissan is going to be remanufactured. Any time you deal with remanufactured, it's always a gamble, but most are generally pretty good. Looking at the choices at Rockauto.com, the AC Delco # 36G0210 is the only one that carries a limited-lifetime warranty and at $167.99 (note including core or shipping charges), is in the middle of the price range of those offered. The other options have 1-3 year warranties. If the hoses are due for replacement, Rockauto has them, too.
