This billet aluminum coolant pipe replaces the factory plastic coolant neck that is a potential failure point in M240i, M340i, M440i, 540i, 740i, 840i, X3, X4, X5, X6, X7, Z4 models. This pipe sends cool coolant from the pump to the engine block. The original is plastic and in a very vulnerable location so it's possible to develop cracks or leaks on the plastic, leading to an annoying coolant leak or even cooling system failure.

This replaces BMW part number 11518482258 (11 51 8 482 258), the original plastic coolant pipe (aka connecting branch) on B58C, B58D, and B58TU engines.

A new o-ring is included.
