Carbon Fiber Subaru WRX / STI Brake Cooling Ducts 2015-2017

The Carbon Fiber Subaru WRX / STI Brake Cooling Ducts (2015–2017) by APR Performance are engineered to deliver efficient airflow to your front brakes, reducing high-temperature buildup during intense driving conditions. Designed with aerodynamics in mind, these ducts utilize the Venturi effect to funnel and accelerate airflow directly toward your brake rotors.

As vehicle speed increases, the duct’s narrowed section compresses and accelerates the air, increasing both pressure and velocity to deliver a high volume of cool air. This helps maintain lower brake temperatures, minimize fade, and extend rotor and pad life — lap after lap.

Constructed using pre-preg carbon fiber reinforced polymer (CFRP), each component is autoclave-cured for exceptional strength, durability, and weight reduction. Finished with a UV-resistant clear coat, these ducts resist environmental damage while maintaining a deep, high-gloss carbon weave finish that complements your WRX / STI’s performance aesthetic.

When paired with appropriate high-temperature hoses (not included), the system ensures consistent cooling efficiency for both street and track applications.
