Carbon Fiber Rear Trunk Spoiler for BMW 4 Series F36 Gran Coupe (2014-2019)
A molded genuine carbon fiber rear trunk spoiler designed for the BMW 4 Series F36 Gran Coupe 4-door. It follows the curvature of the F36 trunk hatch for a factory-style profile, adds a sportier rear silhouette, and is engineered with aero simulation and CAD tooling to reduce drag and add rear downforce for better stability at speed, without blocking rearward visibility. Installation is tape-on with the included double-sided tape, so no drilling or bodywork is required.

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.
