BMW Brake Booster Vacuum Hose 7850595 is a used OEM line from a 3.0L turbocharged I6 engine. This genuine hose (also called a brake booster vacuum line) delivers vacuum pressure from the engine to the booster, enabling power-assisted braking. Over time, the rubber can crack or collapse, leading to a hard brake pedal or a hissing vacuum leak under the hood. Genuine BMW fit for M3 and M4 models.
