Refresh the rear profile of your A3 with a replacement-style diffuser in 3×3 weave carbon fiber. The listed finish is a glossy, double-layer UV-protected clear coat.
Fitment
- Audi A3 8V.5 Base Hatchback, model years 2017, 2018, 2019 and 2020.
- The original listing describes a 4-door hatchback and excludes A3 S line and S3 models.
- Fitment tags on the product also refer to 2-door hatchback trims, which conflicts with the 4-door fitment description. Verify your body style, factory diffuser shape and mounting points before ordering; the hidden vehicle tags have been retained unchanged.
Product details
- Material: 3×3 weave carbon-fiber cloth, as specified in the source.
- Style: replacement rear bumper diffuser.
- Finish: glossy, double-layer UV-protected clear coating, according to the source.
- Package: the source lists self-tapping screws as included; it does not specify the diffuser's piece count.
Installation notes
The original listing recommends professional installation and says to remove the factory diffuser before fitting the replacement. Test-fit the part and confirm alignment before fastening. Self-tapping screws may require drilling; a no-drill installation is not guaranteed. No tested aerodynamic or fuel-economy results are provided.
Before ordering
Check the listed years, body style, trim exclusion and rear bumper design against your vehicle. Contact the seller with clear vehicle and bumper photos if fitment is uncertain.

Ordered the BMW front bumper fog light grille and the fitment was absolutely perfect. Gloss black finish looks factory-fresh and the quality is outstanding. Installation took about 30 minutes — no drilling required. Highly recommend AlchemyRide!

Fast shipping, great packaging, and the part arrived in perfect condition. The grille fits my F23 like a glove — exactly as described. Customer service was also super responsive when I had a fitment question. Will definitely order again.

I've bought aftermarket parts from many stores but AlchemyRide stands out for quality and value. The part was well-made, fit perfectly, and the price was very competitive. My BMW looks aggressive and clean — exactly what I wanted.

Excellent product and super easy to install. The gloss black finish matches my M Sport bumpers perfectly. Shipping was faster than expected and the part was well-packaged. Very happy with my purchase — my car looks completely transformed!
