Rear bumper diffuser with shark-fin corner extensions, Model 3

A fluted lower panel for the rear bumper with two corner extensions. It changes how the back of the car looks and nothing else — nobody has measured it in a tunnel or anywhere else, so that is the whole claim.

Manufacturer-stated fitment.

  • Model 3 — 2017–2023, per the manufacturer

Nobody here has held one of these against a car.

Available by order, subject to fitment and supplier availability. Nothing here is held in stock.

This part is a permanent modification to your car.

Automotive double-sided tape and Self-tapping screws are required to fit it, per the manufacturer.

Holes do not come back. Nothing permanent happens to your car until you have seen exactly where it goes and said yes to it in writing, and if you change your mind at that point you have lost nothing.

These are the manufacturer’s own photographs of the part, not photographs of work this shop has done. Several carry the maker’s sales copy burned into the image. We have not fitted one of these to a car and photographed it, and when we do, that photograph will say so.

What has to be true of your car

  • Fitting instructions are not supplied with the part.

What nobody has settled yet

Published rather than smoothed over. Each of these is resolved against your car before anything is ordered.

  • The gallery may be incomplete. Fewer photographs of this part reached us than exist, and the ones that did could not be matched against the set they came from. What is here is what was actually supplied.
  • Highland fitment is not advertised for this part and we do not claim it.

There is no price on this page. The installer has not given us labor rates for accessory work, so any figure here would be half a number — and a part price without fitting beside it reads as the installed price. Ask and you get the whole thing or nothing.
