Product Details

We at Turner Motorsport weren't happy with the current offerings for E46 M3 diffusers, so we decided to create something new!

Upgrade the exterior styling on your BMW E46 M3 with the Turner In-House designed and engineered Carbon Fiber Rear Diffuser. 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 hand-laid 2x2 pre-preg carbon fiber, this exclusive design from Turner Motorsport will be sure to turn heads!

Make a bold statement and let your BMW stand out with the Turner Carbon Fiber Diffuser!

Designed in-house using state of the art 3d laser scanning and CAD technology for precision fitment
Mounts to existing bumper insert mounting locations with OE hardware
TMS carbon fiber products are made from lightweight, hand-laid epoxy resin pre-impregnated 2x2 twill weave carbon fiber cloth and autoclave cured
Clear coated for excellent finish durability and UV resistance
Can be painted for a color-matched look with standard body shop prep work
