Heater Inlet Pipe, Rein - E46 E39 E53 E83 E85 Z3

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 an OEM heater pipe manufactured by Rein - an original supplier to BMW for many cooling and engine parts. 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.
