CFN Brand Rear Fascia Base Diffuser Assembly for Tesla Model 3 (2023+) | 1582583-00-D

Key Features & Benefits

• OEM-Grade Precision Fit: Mirrors the original diffuser’s contour, mounting points, and aerodynamic curves, aligning perfectly with the Model 3’s rear fascia and bumper. No modifications needed—ensures a flush, factory-installed look without gaps or misalignment that could disrupt airflow.
• Durable Impact-Resistant Construction: Crafted from high-strength ABS plastic with a textured finish (OEM-equivalent material), it resists cracking, scratching, and UV degradation. Withstands extreme temperatures (-40°C to 80°C) and road debris impact, maintaining structural integrity and visual consistency.
• Aerodynamic Performance Restoration: Preserves the Model 3’s original underbody airflow design, reducing drag and optimizing rear-end downforce. Helps maintain the vehicle’s efficiency and stability at high speeds, matching the performance of the OEM diffuser.
• Cost-Effective Aesthetic & Functional Repair: Offers the same fit, durability, and aerodynamic function as OEM at a fraction of the price. Perfect for professional body shops or DIY enthusiasts, avoiding costly dealer replacements while restoring the Model 3’s sleek rear-end appearance.
