Audi A4 B9 RS4 S4 Sedan 4-Door 2017-2022 Mirror Covers Replacement Style Carbon Fiber
Available in stock (20)
Carbon Fiber Replacement Mirror Covers for 2017-2022 Audi A4 B9 / S4 B9 / RS4 B9 (Sedan)
The Audi A4/S4/RS4 B9 platform shares the same exterior door mirror housing geometry across all three variants — one carbon fiber mirror cover set fits the A4 B9, S4 B9, and RS4 B9 Sedan. These direct plug-and-play carbon fiber replacement mirror covers swap the factory plastic mirror housings for genuine 3×3 twill weave carbon fiber, adding a precise carbon detail at the B9's most visible exterior accent point. No painting, no wrapping — full replacement of the factory housing with a carbon fiber unit.
The B9 A4/S4/RS4 is available with or without Audi Side Assist (lane change assist / blind spot monitoring). The SWA sensor is housed inside the door mirror assembly. Choose the correct variant before ordering:
- Without Lane Change Assist ($159.99): Solid mirror housing — no sensor cutout. For B9 vehicles without Audi Side Assist / blind spot monitoring.
- With Lane Change Assist ($129.99): Mirror housing includes the SWA sensor window cutout. For B9 vehicles equipped with Audi Side Assist. Installing the wrong variant will block your SWA sensor.
Key Features
- B9 Platform-Specific Fitment: Direct plug-and-play replacement for the 2017–2022 Audi A4 B9, S4 B9, and RS4 B9 Sedan — all three B9 variants share the same exterior door mirror housing geometry. No modification, no drilling, no painting.
- Full Mirror Housing Replacement: Complete replacement of the factory plastic mirror housing shell — not a stick-on overlay. Installs over the existing mirror mechanism using factory attachment points and the included installation tool. Factory mirror glass, heating, fold motor, and electronics are retained.
- Two Variants for SWA Compatibility: Available with or without the Audi Side Assist (SWA) sensor window cutout — ensure you select the correct variant for your B9's equipment level to maintain full SWA function.
- Genuine 3×3 Carbon Fiber Construction: Premium 3×3 twill weave carbon fiber with UV-resistant high-gloss double-layer clear coat — lightweight and a precise carbon finish at the B9's most visible exterior accent point.
- Installation Tool Included: Removal and installation tool included for panel-clip release — no professional installation required for this component, though care should be taken with mirror glass and fold motor connections.
- UV-Resistant High-Gloss Finish: Double-layer UV-protective clear coat locks in carbon gloss and resists fading and surface hazing over time.

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.
