2015 One unit available for the Xterra hot AC pipe, and I think it fits Armada and Navara (aluminum). There's a known defect in these cars where the part from the factory is plastic and suddenly cracks, causing the engine to overheat and potentially damage it if you don't notice. The solution is to install an aluminum one, and its installation is simple and easy. This part is from the factory, not custom-made, and the final price is 80 SAR.
