Turner Motorsport Gloss Black Rear Diffuser - G80/G82/G83 M3/M4 048254la01KT

Gloss Black Rear Diffuser - G80/G82/G83 M3/M4

Upgrade the exterior styling on your G80/G82 with our In-House designed and engineered ABS Rear Diffuser. Utilizing factory mounting locations and supplied hardware this diffuser is a direct bolt-on upgrade that can be installed directly in place of your factory diffuser. Featuring a deep profile, an aggressive fin design, and extending the entire width of the rear bumper, our exclusive design is sure to turn heads! Our engineers did an absolutely amazing job on this diffuser from the styling to the fit and finish that is guaranteed to stand out in the market.

Pay close attention to the design characteristics of the diffuser. The emphasized outline of the diffuser adds a whole new dimension to the rear bumper bringing out the beautiful body lines of the G80. By adding an aggressive fin design and boxing around the exhaust exits the rear/side view is almost transformed into a whole new sub model that BMW forgot to offer.
