RS4 Style Fog Light Grille for Audi A4 Base/S-Line/S4 B9 2017-2019
Bring RS4-inspired styling to your B9 A4 or S4 with this honeycomb mesh fog light grille, finished in gloss black for an aggressive, track-ready front-end look. Precision-engineered as a direct OEM-fit replacement for the S-Line/S4 bumper, it maintains your factory mounting points and aerodynamic function — this is a clean swap for your existing grille, not an add-on panel.
Molded from durable, OEM-grade ABS plastic for strong impact resistance and a precise factory-like fit, this grille slots straight into place with no cutting, trimming, or permanent modification required.
⚠️ Important — Base vs S-Line fitment (please read before ordering)
- Base trim grilles fit standard, non-S-Line A4 bumpers only — they will NOT fit an S4.
- S4 owners must select an S-Line variant — the S4 uses the S-Line-style bumper shape, and a Base grille will not sit correctly on it.
- If you're unsure whether your A4 has the Base or S-Line bumper, check your existing factory grille shape against the listing photos, or message us with a photo before ordering.
⚠️ Important — ACC (Adaptive Cruise Control) compatibility
This grille is available in both with-ACC and without-ACC versions. The with-ACC variants are designed with a built-in aperture for vehicles equipped with ACC radar sensors, allowing your factory adaptive cruise control to continue functioning normally after installation. Before ordering, please confirm:
- Your vehicle is actually fitted with ACC from the factory (not all B9 A4/S4 trims have this feature) — check your options list or existing grille for a visible radar sensor if you're unsure
- If your car does not have ACC, select one of the without-ACC variants — fitting an ACC-cutout grille to a non-ACC car (or vice versa) can affect fitment and sensor function
- With-ACC variants include the screws required to fit the ACC sensor housing
Installing the wrong variant can interfere with your adaptive cruise control's radar function, so this is worth confirming before you order rather than after installation.
