Transform the rear aesthetic of your BMW 1 Series with our Gloss Black Performance Style Rear Diffuser. Designed specifically for the LCI (Facelift) F20 and F21 models, this diffuser adds a sharp, aggressive edge that perfectly complements the M-Sport body lines.

This specific model features a Dual-Exit (Left & Right) cutout, making it the essential upgrade for M135i or M140iowners, or those performing a dual-exit exhaust conversion on 118i/120i models.

• High-Gloss Finish: Arrives in a deep, Gloss Black finish. It’s UV-resistant and ready to install straight out of the box—no painting required.

• Durable Construction: Manufactured from high-quality ABS plastic, ensuring flexibility, heat resistance, and long-term durability against road debris.

• Aerodynamic Styling: Features the iconic "Performance" finned design, giving your hatchback a wider, more planted stance from the rear.

Technical Specifications

Why Upgrade?

The factory diffuser can often look understated and plasticky, especially on high-performance models like the M140i. Our Performance Style upgrade replaces the dull OEM trim with a striking, reflective finish that frames your dual exhausts and completes the "shadow line" look. It’s the simplest way to give your LCI the aggressive "M-Performance" rear-end presence it was meant to have.

Note: This product is designed specifically for M-Sport bumpers. It will not fit Standard or Sport-Line rear bumpers. Please ensure your vehicle is the LCI (Facelift) model before ordering.
