Glossy Black ABS Rear Bumper Diffuser for BMW 2 Series G42 220i, 230i M Sport & M240i xDrive Coupe 2021-2023

Glossy Black ABS Rear Bumper Diffuser for BMW 2 Series G42 (2021-2023)
A replacement rear diffuser for the G42 coupe's M Sport bumper. It swaps the factory lower panel for a deeper, finned profile in glossy black, which widens the look of the rear end and ties it to the gloss Shadowline trim already on these cars. The part is moulded from quality ABS and finished under a double-layer UV-protected clear coat, so it arrives ready to fit with no painting, and each one is 3D designed, CNC moulded and test-fitted on an actual vehicle.

Ordered the BMW front bumper fog light grille and the fitment was absolutely perfect. Gloss black finish looks factory-fresh and the quality is outstanding. Installation took about 30 minutes — no drilling required. Highly recommend AlchemyRide!

Fast shipping, great packaging, and the part arrived in perfect condition. The grille fits my F23 like a glove — exactly as described. Customer service was also super responsive when I had a fitment question. Will definitely order again.

I've bought aftermarket parts from many stores but AlchemyRide stands out for quality and value. The part was well-made, fit perfectly, and the price was very competitive. My BMW looks aggressive and clean — exactly what I wanted.
