Technical Specifications

Why Upgrade?

The factory diffuser can often look understated and plasticky. Our Performance Style upgrade replaces the dull OEM trim with a striking, reflective finish that highlights your exhaust and completes the "shadow line" look. Whether you’re going for a full de-chrome or just want a more sporting appearance, this is the essential rear-end modification for the LCI 1 Series.

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.
