Product Details

Our Turner G20 M340i/xDrive Gloss Black ABS Diffuser is a beautiful upgrade to the rear end of your BMW. This diffuser features curvature designed to accentuate the G20 body lines, and is designed and engineered in-house for most aftermarket exhausts up to 4" in diameter (not compatible with factory exhaust tips) using state of the art 3D laser scanning and CAD technology for precision OE quality fitment. Turner ABS diffuser mounts to existing bumper insert mounting locations with OE hardware for a simple installation.

Using all factory mounting locations, this diffuser is a direct bolt-on upgrade that can be installed in minutes. Featuring a deep profile, an aggressive fin design, and extending the entire width of the rear bumper, this exclusive ABS design from Turner Motorsport will be sure to turn heads!

Make a bold statement and let your BMW stand out with the Turner Gloss Black ABS Diffuser!

Features & Benefits:
