Rear diffusers
A diffuser fastened under the rear bumper, set square to the panel above it.
Quoted per project. There is no published price for accessory work and this page is not going to invent one. The part, where it comes from, what it takes to fit it and what the car already has on it all move the number, so it is quoted for your project in writing before anything is ordered or fitted.
What the job involves.
A rear diffuser fastens under the rear bumper, below the license plate line. The job is getting it square to the bumper and level to the ground at the same time, which are two different references that rarely agree on a molded part. It is dry-fitted, checked from behind the car at eye height rather than from above, and fastened with the hardware supplied with it.
What you supply or decide.
- Which part, by make and model or by a link.
- Where it is coming from: yours already, or sourced for the project.
- Your Tesla, its year and its trim.
- Whether anything sits in the area already — a tow hitch, a plate frame, an existing valance.
- Whether the car is being wrapped, and in which order you want the two done.
Where the part comes from.
Tell us which part you want and where it is coming from. Some people have already bought the part and want it fitted; some want us to find it. Which of those applies, and what it costs, is settled in writing for your project before anything is ordered or fitted.
The film rule is a film rule. We supply the vinyl on a wrap and we do not install film you bring us, for reasons set out on /scope. That was never a statement about bolt-on parts and it is not one now.
What this does not promise.
- No aerodynamic claim. A diffuser is a part we fasten on, not a result we measure.
- No sensor or camera work. We do not calibrate, modify, relocate or warrant parking sensors, cameras or any driver-assistance system, and if a part would sit across one we tell you before it is ordered rather than after it is on.
- No promise of a factory gap. An aftermarket diffuser is made to its own tolerance, and the gap it leaves against your bumper is the part’s, not ours to correct.
- No exhaust or heat claim of any kind. There is nothing to route and we are not implying there is.
- No manufacturer warranty from us. The part’s warranty is the maker’s.
Fitting a part is not wrapping a car.
So adding this service changes nothing about the wraps. Full-vehicle color changes only, still no partial wraps, and still no chrome delete — that one is film over factory brightwork, which is a wrap technique rather than a part, and it is still work somebody else does better. What is new is that if the thing you want is an actual part, the answer is no longer no.
Why a wrap and a bolt-on part are different operations
These are two different operations and the site keeps them apart on purpose. A wrap is film: nothing comes off your car, the film is cut to each panel’s pattern, and every edge is worked to whatever it meets. Accessory installation is fastening a part on, which is a normal thing to do to a car and an abnormal thing to do during a wrap.
Which cars.
We wrap the Model 3, Model Y and Cybertruck, and those are the cars these parts are fitted to here. The Model S and Model X are legacy cars we don’t take — not for a wrap, and not for a part — so there is nothing on this page we would fit to one. Ask about anything else and you get a straight answer rather than an assumption.
One bay
One studio in Ashburn, Virginia, and one installer. Accessory work books into the same single bay as everything else, which is why there is no parts counter, no fitting bay and no while-you-wait option on this page.
How to ask about a part.
The quote form is the one we already have, and it is the one to use. Its Service dropdown now carries “Accessory and aftermarket installation”, and the links on these pages select it for you — name the part in the details box and that is the whole request. If you came straight to the form, pick that option yourself.
- The part: a make and model, or a link.
- Whether you already have it, or want us to source it.
- Your Tesla, its year and its trim.
- Whether the car is being wrapped, or already is.
- A photograph of the area, if you have one.
On the form: Service → “Not sure yet — help me choose”. Texting works just as well, and for a part it is often faster — a photograph or a link answers more than a form field does.
