Compatibility: Toyota Sienna MK4-XL40 2020+ Material and durability: High-quality, flexible wind deflector designed to resist deformation, bending, or breaking; maintains shape and provides reliable shading. Function and performance: Reduces wind, rain, and dirt intrusion when windows are slightly open; lowers wind noise and smooths the airflow for a quieter, more comfortable ride. Installation: No special hardware or drilling required. Clean the window surface to remove dust and moisture, then apply using pre-cut 3M tape for quick adhesion. Do not wash the vehicle within 72 hours after installation. Use scenarios: - Rainy days: Ventilate the cabin with slightly open windows while keeping rain out, improving comfort on wet commutes. - Sunny days: Provide shade to the interior and reduce heat while maintaining window ventilation. - Highway or urban driving: Minimize wind buffeting and road noise for a calmer, more predictable cabin environment.
