APR Performance Carbon Fiber Brake Cooling Ducts 2018-2021 WRX / STI

The APR Brake Cooling Ducts are designed to funnel large volumes of air directly to your braking system for improved cooling performance. Utilizing the venturi effect, airflow increases in pressure and velocity as it moves from the larger inlet to the smaller duct outlet. When paired with high-temperature brake duct hoses (not included), these ducts help deliver consistent fresh air to reduce rotor temperatures during intense track use.

Managing heat is critical to protecting key components such as brakes, radiators, transmissions, and differentials. APR Air Ducts direct cooling air exactly where it’s needed, helping prevent excessive heat buildup. Constructed from pre-preg carbon fiber reinforced polymer (CFRP), they provide exceptional strength while keeping weight to a minimum.

Features:

Pre-Preg Carbon Fiber Construction
Autoclave-formed using pre-impregnated carbon fiber for high strength and lightweight performance.

UV-Resistant Clear Coat
Finished with a durable UV-resistant clear coat to withstand environmental exposure. Maintain like automotive paint—polish and protect with a quality wax or synthetic sealant.
