Rear Bumper Diffuser Lip with Brake LED For 2018-2023 Infiniti Q50

Fitted to the base of the rear bumper, this diffuser adds visual depth to the Q50's tail while giving underbody air a cleaner path out from beneath the car. It's molded in PP, the same family of plastic used in the factory bumper, so it shares the same give and impact tolerance — flexing under a light knock rather than cracking outright, and standing up to years of outdoor exposure.

Product Features

Two versions are offered depending on what the owner wants: one integrates an LED brake light directly into the diffuser for added visibility and a more finished look, while the other skips the light for a cleaner, more minimal profile. Either way, the mold is taken from the factory rear bumper, so the fit lines up with the stock contour without gaps or awkward transitions.

The diffuser shape itself is functional, smoothing out turbulence and reducing lift at speed. Installation uses either the factory bolt holes or 3M adhesive, and a test-fit before final mounting is recommended. It suits everything from daily driving to track days to a full rear-end refresh.
