Front Left-Hand (LH) Wheel Liner for 2021+ Tesla Model X | 1585128-00-C (CFN Brand)

1. Underbody Component Protection: Acts as a durable barrier between the front left wheel well and critical underbody parts (e.g., front suspension hardware, brake lines, wiring harnesses, and cooling hoses), preventing damage from road debris (gravel, stones, broken glass) kicked up by the left front wheel during driving.
2. Debris & Contaminant Blocking: Blocks mud, rainwater, and road salt from splashing into the wheel well and underbody cavity—avoiding corrosion of metal components (e.g., suspension bolts, brake caliper brackets) and reducing the risk of wiring harness short circuits caused by water intrusion.
3. Aerodynamic & Noise Reduction: Follows Tesla’s factory aerodynamic engineering to guide airflow around the left front wheel, minimizing wind resistance (supporting the vehicle’s energy efficiency) and reducing road noise generated by airflow passing through the wheel well.

• Impact & Wear Resistance: The PP material has a notched impact strength of ≥5kJ/m², resisting cracking from impacts with small stones or curbs; the integrated rib structure enhances structural rigidity, preventing deformation even under long-term pressure from the wheel or road vibration.
• Extreme Environment Adaptability: Withstands temperature fluctuations from -30°C to 85°C, suitable for snowy winters (resists brittleness in low temps) and high-temperature summers (avoids softening or warping); it also resists UV fading (passes 400-hour ASTM G154 UV tests) and chemical corrosion from road salt or car wash cleaners.
• Fit Precision: The liner’s edge contours, mounting holes, and snap-clip positions are 1:1 matched to the Model X’s factory wheel well, ensuring no gaps between the liner and front bumper or fender—avoiding debris leakage into the underbody.

1. Lift the front left side of the vehicle and secure it with jack stands (ensure stable support to avoid safety risks); remove the front left wheel for easier access to the wheel well.
2. Use a trim tool to gently detach the plastic snap clips and bolts that secure the old wheel liner to the front fender, bumper, and underbody frame—note the position of each fastener (there are typically 8–10 total: 5 plastic clips and 5 8mm bolts) to avoid misinstallation.
3. Pull the old liner away from the wheel well, taking care not to damage adjacent components (e.g., fender trim or brake lines); clean the wheel well’s mounting surface with a dry cloth to eliminate dust, mud, or residual adhesive.
4. Align the CFN wheel liner with the wheel well’s mounting points, ensuring the liner’s edges fit snugly against the fender and bumper; snap the plastic clips into place first (you’ll hear a “click” when secure), then tighten the 8mm bolts to 4±0.3 Nm (per Tesla’s official torque specs—over-tightening may crack the liner’s plastic mounting tabs).
5. Reinstall the front left wheel, lower the vehicle, and check the wheel well from the side to confirm the liner is flush with the fender and bumper, with no loose areas or gaps that could allow debris entry.
