MRC Racing Components 3” Aluminum Brake Duct

Get fresh air directly to your brakes where it counts. The MRC Racing Components 3" Aluminum Brake Duct provides a clean, purpose-built mounting point for routing cool air from the front of your car directly to your brake rotors and calipers. Drill a 3-inch hole in your nose or bumper, sandwich the included mesh screen behind the duct, and attach a brake cooling hose to complete the setup.

Pro Tip: Ducted brake cooling is not just for high-horsepower cars. Any vehicle that sees sustained hard braking — whether it is a stock car on a short track or a street car at a track day — benefits from dedicated airflow to the brakes. The difference between consistent braking on lap 20 versus fading brakes is often just proper cooling.
