The Bosch 3397014621 designates a specific Original Equipment (OE) replacement wiper blade designed for the driver’s side. These blades utilize Aerotwin technology, a beam-style design known for its consistent pressure distribution and clean wiping performance across the windshield. This specific part number ensures compatibility with select vehicles requiring this precise fitment. An example application would be a vehicle manufacturer specifying this exact Bosch part as the original equipment on their models.
Choosing OE replacement blades offers several advantages. They maintain the original design specifications for optimal performance and integration with the vehicle’s wiper system. Beam blades, like the Aerotwin, offer superior performance compared to traditional frame-style blades, particularly at higher speeds and in challenging weather conditions. Their consistent contact with the windshield reduces streaking and chattering, leading to improved visibility and safety. The development of beam blade technology represents a significant advancement in wiper blade design, enhancing driving safety and comfort.
