Product Overview
This is a cosmetic/aero-style upgrade for a Q50 owner who wants a more aggressive rear profile or needs to replace damaged add-on trim. The diffuser reshapes the lower bumper appearance while the spoiler adds a matching gloss-black accent at the trunk edge.
Before ordering, use the compatibility information below as a starting point and compare the original part’s position, shape, connectors, mounting tabs and reference numbers whenever available. That extra check matters because trim packages and mid-year production changes can create visually similar parts that do not interchange.
Key Features & Performance
- Changes the lower-body appearance with a more aggressive, performance-inspired profile.
- Provides a replaceable outer edge in an area that is often scraped by curbs, ramps or road debris.
- Vehicle-specific styling follows the listed bumper or rocker-panel shape.
- Test fitting before drilling or applying permanent adhesive is strongly recommended for aftermarket aero pieces.
What Is Included
rear bumper diffuser and rear/trunk spoiler components as shown in the listing
Fitment Notes
Aftermarket Q50 diffusers are often bumper-style specific. Compare the lower bumper contour, exhaust openings and whether the kit includes an LED/brake-light section before drilling or applying adhesive.
Frequently Asked Questions
Is this a genuine OEM part?
No. This listing is for an aftermarket replacement or accessory unless the product page specifically states otherwise. OE and Partslink numbers are used as fitment references.
How should I verify fitment before ordering?
Match the year, model, trim/body style, side or position, connector or mounting layout, and any OE/reference numbers shown above against the part currently on the vehicle. For lighting and grille parts, also compare every factory option, sensor opening and lamp technology.
