Windshield wiper blades are essential equipment on any BMW. As wipers age, the rubber that wipes the rain off and keeps the windshield clean can dry out and crack, resulting in poor performance. Eventually, worn wipers can even damage a windshield. Having a fresh set of wipers on your BMW makes the vehicle safer by increasing outward visibility, particularly when it is raining. BMW recommends changing the blades once a year using OEM Bosch replacements, not cheap aftermarket blades.
