Coolant hose for the BMW N54/N55 3.0L turbo engine cooling system. A direct-fit factory-spec replacement rubber hose that carries coolant between the engine and cooling system components; over time these hoses split at the clamp points, swell, crack, or fail outright, which can lead to coolant loss and overheating if not replaced.

Fitment: BMW N54/N55 models - E82/E88 135i, E90/E91/E92/E93 335i/335is/335xi, E89 Z4 (confirm exact hose position at checkout).
