If you’re looking to restore the rear-end aerodynamics, protection,
or sleek appearance of your 2023 Tesla Model X—whether the original
rear fascia diffuser is cracked, scratched, or damaged from road
debris—this CFN rear fascia diffuser (matching OEM part
1711840-00-A) is the precision-fit solution. As an engineered
replacement (not Tesla OEM), it mirrors the 2023 Model X’s factory
diffuser design, dimensions, and mounting points, ensuring seamless
integration with the rear fascia while preserving the vehicle’s
aerodynamic efficiency and bold visual identity.
Beyond aesthetics, this diffuser plays a key role in the 2023 Model
X’s performance: it optimizes airflow under the rear bumper,
reducing aerodynamic drag (a critical factor for maintaining EV
range) and minimizing rear-end lift at highway speeds—enhancing
stability during fast driving. Unlike generic diffusers that may
misalign with the Model X’s rear fascia or disrupt airflow, this
CFN part follows the exact contour of the 2023 Model X’s rear
bumper, with precision-cut edges that fit flush against the fascia
(no gaps or unevenness) and pre-drilled mounting holes that align
with the factory brackets.
Durability is built for real-world road conditions:
- Material: Made of impact-resistant, glass-reinforced ABS plastic (same as
OEM)—tough enough to withstand scrapes from curbs, hits from road
gravel, and exposure to rain, snow, or road salt. It won’t crack in
cold temperatures or fade under intense sunlight, maintaining its
deep, factory-matching finish for years.
- Finish: A smooth, matte-black coating (calibrated to the 2023 Model X’s
rear fascia) resists scratches and hides minor road wear, keeping
the rear end looking sharp without the need for repainting.
Installation is straightforward with basic tools (professional
fitting recommended for perfect alignment):
- Clean the 2023 Model X’s rear fascia to remove dirt or debris, then
remove any remaining hardware from the old diffuser (e.g., screws,
clips).
- Align the CFN diffuser with the rear fascia’s mounting
points—ensure the edges line up with the bumper to avoid airflow
disruption.
- Secure the diffuser using the original factory screws (or included
hardware, if replacing missing parts), tightening gently to avoid
damaging the fascia or diffuser.
Note: This rear fascia diffuser is exclusively for the 2023 Tesla Model X. It won’t fit 2022 or older Model X variants (different rear
fascia designs) or other Tesla models (3/Y/S). It’s ideal for
replacing damaged OEM diffusers, restoring aerodynamic performance,
or refreshing the 2023 Model X’s rear appearance—keeping your
vehicle both functional and true to Tesla’s premium design
language.
