This genuine BMW Vacuum Hose, specifically part number 11668606505, is engineered to connect your brake booster to the intake manifold. A properly functioning vacuum hose is critical for the power brake system, as it allows the brake booster to amplify the force you apply to the brake pedal. Over time, vacuum hoses can degrade due to heat, age, and exposure to engine bay contaminants. This degradation can lead to cracks or leaks, compromising the vacuum supply to the booster. Symptoms of a failing vacuum hose may include a hard brake pedal, reduced braking assist, or a hissing sound from the engine bay. Replacing a worn or damaged vacuum hose with this OEM BMW part ensures that your braking system receives the consistent vacuum pressure it needs for safe and effective operation. Trust in genuine BMW parts to maintain the integrity and performance of your vehicle's essential systems.
