Rear Trunk Soundproof Acoustic Cotton Liner for Tesla Model 3 Highland 2024+
Add an additional acoustic-insulation layer to the rear trunk of your Model 3 Highland. The high-density acoustic cotton is shaped to follow the trunk contours and helps reduce road noise, tire hum and external vibration reaching the cabin from the rear of the vehicle.
🔇 Rear-Trunk Noise Damping
The supplier states that the high-density acoustic material helps reduce road noise, tire hum and vibration entering through the rear trunk area.
🧵 High-Density Acoustic Cotton
Made from upgraded high-density acoustic cotton designed for sound absorption and additional thermal insulation inside the trunk area.
🔩 Factory-Point Installation
Designed to align with the vehicle's existing reserved screw holes for secure installation without drilling or adhesive.
🧹 Removable for Cleaning
The liner can be removed for vacuuming or cleaning and then reinstalled using the original mounting locations.
Additional Acoustic Insulation for the Rear Trunk
Helps Reduce Road & Tire Noise
The acoustic liner adds another sound-absorbing layer around the rear trunk area, helping reduce some of the noise transmitted through the rear body structure.
Helps Dampen Small Vibrations
The high-density material can help absorb some vibration and resonance around the covered trunk surfaces.
Additional Thermal Insulation
The supplier also describes the material as providing thermal-insulation properties in addition to acoustic absorption.
⚠️ Noise Reduction Will Vary by Vehicle & Road Surface
This product is intended to help reduce some noise and vibration transmitted through the rear trunk area. It does not make the vehicle completely soundproof, and the final result can vary with tires, road surface, speed, suspension, cabin condition and other noise sources.

For accuracy, this listing should be treated as Highland 2024+ only.
Designed Around Normal Trunk Function
The supplier states that the slim fitted liner is designed not to obstruct the trunk latch, trunk lighting or normal storage capacity when correctly installed.
Bolt-On Installation Using Factory Points
1. Empty the Rear Trunk
Remove loose cargo and any items that may interfere with access to the installation area.
2. Identify the Factory Mounting Points
Locate the original reserved screw holes used by the liner.
3. Test-Fit the Acoustic Panels
Position the liner against the trunk contours and confirm that the mounting points line up correctly.
4. Secure Using the Existing Locations
Fasten the liner through the original mounting points as intended.
5. Check Panel Alignment
Make sure all sections sit flat without pinching nearby trim or wiring.
6. Verify Trunk Operation
Confirm that the trunk latch, lights, storage areas and moving components continue operating normally.
No Drilling or Adhesive Required
The supplier states that installation uses the vehicle's original reserved screw holes. No drilling, glue or permanent adhesive installation is required.
Cleaning & Maintenance
Routine Cleaning
Use a vacuum or soft brush to remove dust and loose debris from the acoustic surface.
Removable Design
The liner can be detached when deeper cleaning is required.
Dry Before Reinstallation
If the material becomes damp during cleaning, allow it to dry fully before reinstalling it in the trunk.
