Cylinder Head Coolant Vent Pipe, BMW - F10 550i, F13 650i, F02 750i, X5/X6 50i

Coolant leaks near the turbos on the N63 engine may be traced to this vent pipe for the cylinder heads. The Y connection on this hose is plastic and prone to cracking and leaking near the turbos. This pipe was used on early models of the N63 V8 engine: 2011-2013 F10 550i, 2012 F12/F13 650i, and 2009-2012 F01/F02 750i. These models use the N63 engine, not the N63TU engine that came out in 2013. Note the years as the cooling system was re-designed on the later models.

This is a Genuine BMW N63 vent 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.
