This hose runs from the auxiliary radiator in the right side wheel well to the water pump Feed Line on N20 and N26 engines used on F22 228i, F30 320i/328i, and F32 428i models.
This hose only fits models with Automatic Transmission. The automatic models received an extra small radiator in the passenger side wheel well for cooling the transmission fluid.
This is an OEM F22/F30/F32 aux radiator hose manufactured by Rein Automotive - the original supplier to BMW for this part, as well as many other cooling components. As the OEM it meets all of BMW's original design, fitment, and performance requirements and is TUV approved. OEM 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.
