BMW ALPiNA B4 D4 GT G26 LCI Bumper Grille Grill flaps Complete
complete ALPINA B4/D4 GT (G26 LCI) front bumper assembly can be tricky since these parts are often exclusive to ALPINA-authorized dealers or specialized retailers. The G26 LCI (Life Cycle Impulse/Facelift) specifically features a updated front end with integrated aerodynamic elements.
A “Complete” assembly for the B4/D4 GT typically includes the main bumper cover, the ALPINA-specific front spoiler lip, and the complex air flap system.
Key Components of the Assembly
-
Bumper Cover: The base structure, often shared with the BMW M440i/M-Sport but modified for ALPINA cooling. BMW ALPiNA B4 D4 GT G26 LCI Bumper Grille Grill flaps Complete
-
ALPINA Front Spoiler: The iconic lower lip featuring the ALPINA wordmark. For the GT models, this often includes small black-painted canards.
-
Bumper Grilles: The central and side grilles. On the B4 GT, the kidney grille features distinct silver bars.
-
Air Flap Control: The active “flaps” that open or close for aerodynamic efficiency and cooling.

Shopping Tips for G26 LCI Parts
-
VIN Verification: Because the LCI (2025/2026 models) changed the mounting points for grilles and sensors, always provide your VIN to the seller to ensure the air flap motor and sensor brackets align correctly.
-
Shadowline vs. Standard: The GT models often come with Shadowline (Black) accents. Ensure your grille choice matches your window trim and mirror caps.
-
Complete Kits: Some European retailers like Auto-Doc or Schmiedmann offer “Bumper Kits” (e.g., Diederichs 1224251) which include the grilles and mounting hardware, but the specific ALPINA lip is usually sold separately.
