The X3 G01 M40i LCI SQ Style Dry Carbon Fiber Diffuser is a performance-oriented rear aero upgrade that replaces factory components with a full carbon fiber assembly built for drivers who want their build to stand out from all angles.
Molded from genuine pre-preg dry carbon fiber, each piece is cured under controlled heat and pressure for a tighter weave, superior strength-to-weight ratio, and a deep, UV-resistant gloss finish that holds up over time.
Fitment
Please verify compatibility with your specific vehicle configuration before ordering.
We strongly recommend professional installation by a shop experienced with carbon fiber work. Improper installation risks damage to the component or surrounding trim that is difficult to reverse.
