Installation notes
Test-fit and align the spoiler before applying tape. Clean and dry the mounting surface and follow the adhesive manufacturer’s preparation and curing instructions. Adhesion depends on surface condition and installation conditions, so a no-modification installation is not guaranteed for every vehicle. Professional installation is recommended if the fit or surface condition is uncertain.
Before ordering
Confirm the sedan body style, year, trim and trunk profile against your vehicle. The source does not provide test data confirming changes to drag, downforce, stability or fuel economy.

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!
