BMW G22, M440i Carbon Fibre CSL Style ACC Front Grille

BMW G22, M440i Carbon Fibre CSL Style ACC Front Grille

Transform the front of your G22 4 Series with the CSL Style Carbon Fibre Front Grille, an open-frame assembly with a horizontal centre blade in place of the usual vertical slats. This is the ACC version, machined with the radar apertures required by cars fitted with Active Cruise Control.

Manufactured from dry carbon fibre with a high-gloss twill finish, the grille reproduces the CSL layout: open upper and lower sections either side of a solid carbon centre bar spanning the full width. Two sensor ports are formed into that centre bar so the factory ACC radar and its mounting are unobstructed.

It suits a build where the front end is meant to be the statement, and it is the single most transformative exterior change available for the G22.

Key Features

ACC Radar Compatible

Sensor apertures are formed into the centre blade, so the grille clears the Active Cruise Control radar and its bracket. Cars without ACC are covered by the standard version of this grille.

Dry Carbon Fibre Construction

Manufactured using a dry carbon process, chosen for its rigidity across a large open frame and the depth of its finish.

CSL Layout

A solid horizontal centre blade replaces the vertical slats, the defining feature of the CSL front end.

Open Frame Design

Upper and lower sections are left open, giving the front far more depth than a slatted grille.

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 outright rather than detailing it, and is the most visible exterior upgrade available for the G22.

Retains Driver Assistance

Because the radar aperture is built in, Active Cruise Control continues to operate as standard.

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.

Please Note

Professional installation is strongly recommended.

This is a complete replacement grille. The factory grille is removed.

The ACC radar sensor and its bracket are transferred from the original grille. Radar alignment should be checked after installation.

Any camera 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.
