Bought this wheel arch liner: 1 Pair Front Wheel Arch Soundproof Cotton Protective Pad For Tesla Model 3 17-19 | eBay Took a long time getting here. Installation took a little over an hour. No instructions. Pretty obvious how to install it, though it's not clear from the images that the liner fits OVER the existing plastic wheel arch liner. It doesn't replace it, it fits over. My concern was whether the included clips would be long enough. Turns out they are longer than the OEM clips. My hope is that the sandwich of existing plastic liner with additional fabric liner will reduce the sound coming from the wheel area. I drove it about 10 miles on the highway after installation, and it seems quieter. Probably mostly placebo, but placebo works for me. So, jack up the front corner, and remove the wheel. Remove the 15 or 16 plastic clips. You don't need to take out the plastic wheel liner in order to do the install, but I did, just to look behind it. Here's the view. No pedestrian speaker. And with the liner installed, OVER the existing plastic liner. Very easy to do. You actually have enough clips to fill any empty spots, where Tesla decided not to fit a clip. The only tricky spot. You have to remove that small hex bolt. Can't remember if it's 11mm or 12mm. When you do, you'll see that the liner is tucked under the plastic undertray, and there's one clip that's hidden. It's all obvious once you remove the bolt. It's not difficult, other than the clip is hidden.
