This used OEM BMW Brake Booster Vacuum Hose / Line, part number 8649422, was removed from a donor vehicle. Also known as a brake booster vacuum line, it supplies engine vacuum to the brake booster for power-assisted braking. A cracked or leaking hose can cause a hard brake pedal and reduced brake assist, compromising stopping feel. This specific line fits the BMW Z4 with 2.0L turbocharged I4 or 3.0L turbocharged I6 engines.
