About Duct Spoiler / Air Scoop
Brake Duct Spoilers & Air Scoops - Enhanced Brake Cooling for Road & Track Use

Brake duct spoilers and air scoops are aerodynamic cooling components designed to direct airflow toward the brake discs and calipers, helping to reduce operating temperatures during spirited road driving, track days, and motorsport use. By increasing airflow to critical braking components, these parts improve heat dissipation, reduce brake fade, and help maintain consistent braking performance under heavy load.

Available from Design911, brake duct spoilers and air scoops are a proven upgrade for performance-focused vehicles where standard brake cooling is insufficient for repeated heavy braking.

What Do Brake Duct Spoilers & Air Scoops Do?

Brake duct spoilers and air scoops manage airflow around the braking system.

Core Functions:

  • Channel cool air directly toward brake discs and calipers.
  • Reduce brake operating temperatures.
  • Help prevent brake fade during repeated heavy braking.
  • Improve braking consistency and pedal feel.
  • Support high-performance and track-focused braking systems.
  • By improving airflow, these components help braking systems operate within optimal temperature ranges.

Why Do Brake Duct Spoilers & Air Scoops Fail?

Brake cooling components are exposed to harsh environments.

Common Causes of Wear or Failure Include:

  • Impact damage from road debris or kerbs.
  • Heat exposure from prolonged braking.
  • Material fatigue due to vibration and airflow stress.
  • Incorrect fitment or mounting damage.
  • Environmental exposure to moisture and road contaminants.
  • When duct spoilers or air scoops are damaged or missing, brake temperatures can rise, reducing braking efficiency and increasing component wear.

Why Replace or Upgrade Brake Duct Spoilers & Air Scoops?

Replacing damaged or worn brake cooling components restores effective airflow and braking reliability.

Key Benefits:

  • Improved brake cooling and reduced fade.
  • More consistent braking performance under load.
  • Extended life of brake discs, pads, and fluid.
  • Ideal upgrade for fast road and track use.
  • Helps protect braking components from heat-related damage.
  • Brake duct spoilers and air scoops are an essential upgrade for vehicles subjected to demanding braking conditions.  


Highlights

  • Aerodynamic brake cooling components.
  • Direct airflow to brake discs and calipers.
  • Reduce brake fade and thermal stress.
  • Suitable for road, fast road, and track use.
  • Essential for performance braking setups.
