BMW G20/G21, M340i LCI Carbon Fibre Single Slat Front Grille

BMW G20/G21, M340i LCI Carbon Fibre Single Slat Front Grille

Replace the kidneys on your LCI G20 or G21 M340i with this Single Slat Carbon Fibre Front Grille, a complete assembly with a carbon surround and gloss black vertical bars.

Manufactured from carbon fibre with a high-gloss twill finish, the grille is supplied assembled and fits in place of the factory item. The single-slat bar pattern is cleaner and more upright than the standard grille, and the carbon runs the full perimeter of both kidneys.

It suits an owner who wants the front of the car changed rather than detailed, and it is the most visible upgrade available at the front.

Key Features

Carbon Fibre Surround

The outer frame is moulded in carbon with a gloss twill finish, chosen for rigidity across the full grille width.

Single Slat Bar Design

Upright bars in gloss black replace the factory slats, giving the front a cleaner and more purposeful face.

Complete Assembly

Supplied assembled rather than as separate frame and slats, so it fits as a single unit.

Pre-Drilled Mounting Points

Mounting tabs are formed into the moulding at the factory locations, so the grille locates against the bumper without fabrication.

High Gloss Twill Finish

A clear gloss finish over a consistent twill weave, matched to the look of factory BMW M Performance carbon components.

Performance Benefits

Transformed Front End

Changes the face of the car rather than detailing it, making it the most visible front upgrade available.

Improved Aerodynamic Profile

Designed to complement the vehicle's aerodynamic profile and help manage airflow entering the front of the car.

Lightweight Exterior Upgrade

Carbon fibre construction keeps the added mass minimal.

Completes Your Carbon Fibre Build

Matches the weave and finish of the rest of the Proven Performance Parts carbon range for a consistent exterior package.

Vehicle Fitment

BMW G20 M340i LCI (2023+)

Designed for the LCI front end introduced for the 2023 model year. It is not designed to fit the pre-LCI G20 or G21.

Please Note

Professional installation is strongly recommended.

This is a complete replacement grille, supplied with slats. The factory grille is removed.

Any camera, sensor or badge mounted to the original grille may need to be transferred.

Minor preparation, alignment or adjustment may be required during installation to achieve optimal fitment.

Due to the nature of carbon-fibre manufacturing, slight variations in weave pattern may occur between products.
