This part is listed by BMW as BMW part number 11537558899 (11 53 7 558 899) and is described as "Water Pipe, Feed" by BMW. This is the main coolant supply line (pipe) for the front turbo on many N54 twin turbo engines, the turbo that operates on cylinders 1-3, located at the front of the engine. 

Are you replacing your worn or failed N54 front turbo? If so, you should consider replacing any additional hoses, seals and lines that are connected to it, as these tend to wear and fail as well. 

This coolant pipe is used on many chassis and model BMWs, including E9X 335i, 335is & 335xi (E90, E92, E93), E82 135i and 1M Coupe, E60 535i & 535xi, E89 Z4 35i & 35is, F01/F02 740i and 740Li.

For N54 (twin turbo) engine only. Not for most cars after 2010, with the exception of the Z4 35i / 35is, E82 1M Coupe (2011), and E92 335is, which used the N54 engine beyond the 2010 model year. For other cars listed, this pipe was for the 2007, 2008, 2009 and 2010 model year. 

This is a Genuine BMW N54 water pipe 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.
