Replacement Lower Bumper Grille Set

Give Your B9 Front End a More Aggressive, Coordinated Look

Replace the factory lower side grilles with an RS4-inspired honeycomb design that visually connects the outer bumper openings with an aftermarket honeycomb center grille.

Replacement Installation

Replaces the original left and right lower bumper grilles rather than covering them with adhesive trim.

Matched Left and Right Pair

A complete two-piece set creates a balanced appearance across both sides of the front bumper.

RS-Inspired Honeycomb

The open mesh pattern gives the lower bumper a cleaner and more performance-oriented appearance.

Vehicle-Specific Options

Separate configurations are available for different model years, ACC equipment and accent finishes.

Designed to Finish the Entire Grille Conversion

Changing only the center grille can leave the original lower bumper inserts looking visually disconnected. These replacement side grilles extend the honeycomb theme toward both corners of the bumper for a more complete front-end transformation.

Choose a gloss black accent for a full blackout appearance or a silver accent to retain contrast with the vehicle’s original exterior trim.

Vehicle Fitment

Compatible Vehicles

2017–2019 Audi A4 S line B9
2018–2019 Audi S4 B9
Sedan models with the compatible S line or S4 front bumper

Not Compatible With

Check Your ACC Configuration Before Ordering

Some B9 vehicles are equipped with Adaptive Cruise Control sensors located behind the lower bumper grille area. The ACC and non-ACC versions are not interchangeable.

Select “With ACC” only when your original lower grilles have the corresponding sensor locations. The vehicle’s electronic radar sensors are not included and must be retained from the vehicle.

Choose the Correct Configuration

Vehicle	Model Year	Sensor Configuration	Available Finish
Audi A4 S line / S4 B9	2017–2018 A4 / 2018 S4	Without ACC	Gloss Black or Silver
Audi A4 S line / S4 B9	2017–2018 A4 / 2018 S4	With ACC	Gloss Black or Silver
Audi A4 S line / S4 B9	2019	Without ACC	Gloss Black or Silver

Vehicle equipment can vary within the same model year. Compare the product option image with your original lower bumper grille before ordering.

Replacement Installation

Confirm the model year, S line or S4 bumper and ACC configuration.
Remove the original left and right lower bumper grille inserts.
Transfer any required factory sensors, brackets or related components.
Align the replacement grille tabs with the corresponding bumper mounting points.
Check that all edges and clips are fully seated before reassembling the bumper.

Installation note: Front bumper access or removal may be required depending on the vehicle configuration. Professional installation is recommended, especially on ACC-equipped vehicles.

What Is Included

1 × Driver-side lower bumper grille
1 × Passenger-side lower bumper grille
ACC-compatible covers or mounting pieces only when shown with the selected ACC configuration

Adaptive cruise radar sensors, wiring, center grille, emblems and lighting components are not included unless specifically stated in the selected option.

Frequently Asked Questions

Is this an overlay that attaches over the original grille?

No. This is a replacement-style product. The original lower bumper grille inserts must be removed before installation.

Will it fit a standard non-S line Audi A4?

No. The standard A4 bumper uses a different lower grille shape and mounting layout. This product is designed for the compatible S line and S4 bumper only.

How do I know whether my vehicle has ACC?

Inspect the original lower bumper grilles for factory radar sensor locations or check the vehicle’s equipment list for Adaptive Cruise Control. When uncertain, send us a clear front-view photo before ordering.

Are fog lights or ACC sensors included?

No electronic sensors or lighting components are included. The ACC configuration only provides the compatible grille openings and related covers shown in the selected option.

Does the package include both sides?

Yes. One order includes a matched driver-side and passenger-side grille set.

Will this fit a 2020 or newer A4 or S4?

No. The 2020 and newer B9.5 facelift bumper uses a different grille design. Select a product specifically made for the B9.5 platform.

Complete the Honeycomb Front-End Conversion

Pair the lower side grilles with a matching RS4-style center grille for a consistent honeycomb pattern across the entire front bumper.
