N15 Design E46 M3 Lower Fender Duct

(1 customer review)





These lower fender ducts serve to reduce excess air pressure within the wheel well, thus reducing lift on the front axle while improving drag in the wheel area.


Manufactured from durable Nylon 12 plastic, they are impact resistant and can be finished or left bare. They have an excellent surface finish out of the box and can withstand impacts from road and track debris without damage.


Installation is simple with included cutting templates for both the fender and the fender liner. The duct has been contoured to avoid any cutting of any structural components behind the fender, resulting in a safe and easy installation while still maintaining optimal aerodynamics.

    Great option for those that want improved aero without sacrificing aesthetics. Install was pretty easy overall. The hardest part is cutting the fender, but a template is provided so you’ll be fine as long as you take your time.
