This is the hose that carries coolant from the water pump to the engine block, auxiliary radiator, and oil filter housing on N20/N26 engines with automatic transmission in the F22 228i, F30 320i/328i, F32 428i, X1 28i, and Z4 28i. BMW calls it a "Feed Line" and it's a central hose assembly on the N20 cooling system.

Important Fitment Notes:
1. fits with automatic transmission only. One connection on this hose runs to the auxiliary radiator in the passenger side wheel well.
2. this hose part number only fits with engines that use an aluminum oil filter housing (not plastic). Most cars have been updated to an aluminum housing after a factory BMW replacement.

This is a Genuine BMW coolant feed line with a two year warranty. Buying a Genuine part will usually be more expensive than an OEM or aftermarket brand but you are assured that it meets BMW's designs for fitment, performance, and longevity. It will also be the very latest design, incorporating any updates or revisions that an aftermarket brand typically will ignore.
