This is the plastic heater pipe mounted on the side of the engine block under the intake manifold. It carries hot coolant from the engine block to the heater core inlet on the firewall and is prone to cracking and leaking over time. When removing your intake manifold (such as for crankcase vent replacement) it's the perfect time to replace this pipe.

This is a Genuine BMW heater 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.

BimmerWorld Tip: If you are replacing this inlet pipe on an E46, E39, E85, Z3, or Z4 chassis, it's not uncommon for the return line to break off, often right at the block. If yours hasn't broken yet, now is a great time to prevent it down the road. For this reason we recommend picking up the heater return pipe as well, part # 11537502525.Rein, listed in the related items below. We also have an upgraded metal version, part # 11537502525.URO also listed below.
