This is the hose that returns warm coolant from the automatic transmission oil cooler (heat exchanger) back to the radiator on N20/N26 engines with automatic transmission in the F22 228i, F30 320i/328i, F32 428i, X1 28i, and Z4 28i.
This is a N20 cooling hose manufactured by Rein Automotive (CRP) - a front-line supplier of original equipment, private label, and in-house engineered replacement parts. Rein replacement products meet or exceed all of BMW's original design, fitment, and performance requirements and they carry out testing with ISO and German TUV for quality control. Rein parts are the best alternative to more expensive Original BMW parts because they are virtually identical without the inflated price tag. This part has a two year warranty.
