E46 Carbon Brake Ducts

Our E46 Carbon Brake Ducts offer an extremely lightweight and race-quality autoclaved carbon fiber solution for brake-cooling inlets. Designed to fit the E46 M3 and Non-M E46 M Sport front bumpers, these ducts have also been proven to work well with most aftermarket replica bumpers.

Installation Tip: We typically use 4 rivets - 2 at the top and 2 at the bottom - to attach these to the bumper cover on race cars. If you prefer not to drill into your bumper cover, you can attach them with either brackets or high-strength adhesive. 

• Race-quality autoclaved carbon fiber
• Lightweight and rigid constuction
• Ideal fit for M3, M Sport and many aftermarket replica bumpers
• Fully functional to maximize brake cooling

Note 1: Due to the variety of attachment possibilities and methods, hardware and hose clamps are not included with these ducts.

Note 2: these will replace your original brake cooling ducts. Stock brake ducts cannot be used with these.
