Fitment warning: The original title and main description specify GLA45 AMG, but an older fitment line also names GLA180, GLA200, and GLA250. Compatibility with those non-GLA45 variants has not been verified. Confirm your rear bumper and factory diffuser shape against the product photos and check your VIN or bumper part details before ordering. Do not assume that all X156 bumpers share the same diffuser.

Installation Guidance
Professional installation is recommended. Check how the factory diffuser attaches, test-fit this part, and confirm bumper clearance and all mounting points before fastening. The old description says no modifications are needed but also lists self-tapping screws; those screws may require drilling or a permanent bumper modification. Verify the actual mounting method with your installer.
Frequently Asked Questions
Does it fit a GLA250? The old fitment line mentions GLA250, but the title and main description name GLA45 AMG. GLA250 fitment is not confirmed; compare bumper parts and verify compatibility first.
Does it guarantee an aerodynamic improvement? No measured performance data was supplied, so this listing does not promise a downforce or handling gain.

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.

Excellent product and super easy to install. The gloss black finish matches my M Sport bumpers perfectly. Shipping was faster than expected and the part was well-packaged. Very happy with my purchase — my car looks completely transformed!
