The diffuser comes unassembled and you assemble the diffuser and then connect to your Tesla 3 Highlands rear bumper using the included screws. If you do not want to use the screws we can send you double sided automotive tape. The tape is strong enough to hold the diffuser in place however it would not be as strong as the screws so there is always a small chance it could fall off however using the double sided automotive tape means you do not have to drill into your original bumper.
