BMW E46 3 Series 4-Door Sedan 1998–2001 Chrome Kidney Grille Replacement – Single-Slat Chrome-Plated Front Hood Grille | Replaces Part No. 51138208489, 51138208490

Restore the classic front-end appearance of your BMW E46 with this chrome kidney grille replacement designed for pre-facelift 1998–2001 BMW 3 Series four-door sedans. Featuring the distinctive BMW dual-kidney design, a chrome-plated finish, and factory-style vertical slats, this replacement grille provides a clean, refined appearance while preserving the recognizable styling of the original E46 front end. Whether your existing kidney grilles are faded, cracked, scratched, missing, or damaged from everyday driving, replacing them offers a straightforward way to refresh your BMW's exterior. The grille is designed around the original pre-facelift hood opening, helping maintain the vehicle's intended appearance without requiring a modern facelift conversion.

The BMW kidney grille is one of the most recognizable design elements of the 3 Series. Positioned at the front of the hood, the two-piece grille arrangement creates the distinctive visual identity that has characterized BMW vehicles for generations. On the E46 sedan, the chrome grille complements the vehicle's headlights, hood contours, and front bumper, creating a balanced factory-inspired appearance.

Over time, factory grille assemblies can deteriorate due to sunlight, road debris, weather exposure, repeated washing, and ordinary wear. Chrome finishes may become dull or discolored, while plastic mounting tabs can weaken or break. A loose or damaged grille can detract from the vehicle's appearance and may become insecure within the hood opening. Replacing worn grilles can restore a cleaner exterior finish and help maintain secure mounting when the surrounding attachment points remain intact.

This replacement features a chrome-plated appearance with a traditional single-row vertical-slat design. Unlike double-slat aftermarket kidney grilles, the single-slat style retains a more conventional E46 aesthetic. The grille openings preserve the front-end ventilation arrangement while the chrome finish adds visual contrast against the painted hood and surrounding bodywork.

Designed for the original 1998–2001 pre-facelift E46 sedan front-end configuration, this grille is intended to install into the factory hood openings using the corresponding retaining-tab arrangement. Correct fitment depends on the vehicle's body style, production date, hood design, and the condition of the mounting locations. The pre-facelift E46 grille shape differs from the revised design introduced on later facelift sedans.

For BMW owners restoring an older E46 or replacing damaged exterior trim, this chrome kidney grille provides a practical appearance upgrade without changing the vehicle's original design language. It is suitable for factory-style restoration, routine exterior maintenance, or refreshing the front end of a daily-driven BMW 3 Series.

Important Fitment Information

• Fits the pre-facelift E46 sedan body style, not every BMW E46 produced during the listed years.

• BMW E46 production began in 1998 in certain markets; North American sedan applications generally begin with the 1999 model year.

• The E46 sedan received a front-end facelift for the 2002 model year in North America, with production changes beginning during 2001.

• Vehicles produced near the facelift transition should be checked using their production date and original grille design.

• E46 coupes and convertibles use different grille configurations and should not be assumed compatible.

• Fitment for the E46 Touring/wagon may overlap with sedan applications, but this listing is specifically intended for the four-door sedan. Verify Touring compatibility separately.

BMW and specialist parts catalogs distinguish the early sedan grilles from later facelift versions and from coupe/convertible grilles. 

Engine Compatibility

Because the kidney grille is an exterior body component, compatibility depends on the vehicle's chassis, hood design, and production date, rather than its engine configuration.

Potential pre-facelift E46 sedan engine applications include:

BMW Four-Cylinder Gasoline Engines

• M43B16 – 1.6L

• M43B19 – 1.9L

BMW Inline-Six Gasoline Engines

• M52TUB20 – 2.0L

• M52TUB25 – 2.5L

• M52TUB28 – 2.8L

• M54B22 – 2.2L

• M54B30 – 3.0L

BMW Diesel Engines

• M47 – 2.0L Diesel, select early E46 sedan applications

• M57 – 3.0L Diesel, select early E46 sedan applications

Engine availability varied by market and model year. Engine compatibility does not override the requirement for the correct pre-facelift sedan hood.

OEM Reference Part Numbers

Product Configuration Note: The supplied product title does not specify whether this listing includes one grille or a complete left-and-right pair. Confirm the actual package contents before advertising it as a two-piece set.

Installation

• Designed as a factory-style front hood kidney grille replacement for compatible BMW E46 pre-facelift sedans.

• Park the vehicle securely on a level surface before beginning installation.

• Switch off the engine and allow the front-end components to cool if the vehicle was recently driven.

• Open the hood to access the rear of the kidney grille mounting locations.

• Inspect the existing left and right grille assemblies for cracks, broken retaining tabs, or loose mounting points.

• Examine the surrounding hood openings for damage, distortion, corrosion, or previous body repairs.

• Identify the grille being replaced and confirm the correct left-side or right-side orientation.

• Carefully access the original grille's retaining clips from behind the hood where possible.

• Release the mounting tabs without applying excessive force to the surrounding hood or grille trim.

• Remove the original grille assembly from the hood opening.

• Avoid pulling forcefully against clips that remain engaged.

• Clean accumulated dirt, wax residue, and debris from the grille opening.

• Inspect the mounting slots and attachment surfaces before installing the replacement.

• Compare the new grille with the original component to confirm its shape, size, slat arrangement, and mounting-tab locations.

• Check that the replacement grille corresponds to the correct side of the vehicle.

• Align the replacement grille with the factory hood opening.

• Carefully position the retaining tabs into their corresponding mounting locations.

• Apply controlled, even pressure until the grille is fully seated and secured.

• Avoid striking the grille or forcing the chrome-plated surfaces against the hood.

• Confirm that the outer grille frame sits evenly against the hood.

• Inspect the spacing between the grille and the surrounding painted surfaces.

• Gently check that the installed grille does not move excessively or rattle.

• Repeat the procedure on the opposite side if replacing a matched pair.

• Close the hood carefully and inspect the alignment of both grilles from the front of the vehicle.

• Verify that the hood opens and closes normally and that neither grille interferes with the hood latch mechanism.

Installation Guidance

The original E46 kidney grilles typically use integrated retaining tabs for attachment to the hood.

Installation normally does not require electrical wiring, electronic coding, or calibration.

However, damaged mounting tabs, modified hoods, or previous collision repairs may prevent a replacement grille from seating correctly. Any damaged mounting locations should be repaired before installation.
