Carbon Fiber Subaru WRX/ STI Type RA Rear Bumper Ducts 2015-2021

Direct OEM Replacement on Subaru RA ONLY.

The Carbon Fiber Subaru WRX/STI Type RA Rear Bumper Ducts (2015–2021) by APR Performance are precision-engineered to improve airflow and cooling efficiency while adding a race-inspired aesthetic to your vehicle.

These ducts help reduce heat buildup in the rear section by channeling airflow more effectively around and out of the bumper area. This enhanced cooling performance aids critical rear-mounted components such as the differential and brakes, minimizing heat saturation during high-performance driving.

Constructed using pre-preg carbon fiber reinforced polymer (CFRP) and cured in an autoclave at high temperature and pressure, these ducts offer superior strength-to-weight ratio and durability. The UV-resistant gloss clear coat ensures long-lasting protection against fading while highlighting the carbon fiber weave’s deep finish.

Designed for the 2015–2021 Subaru WRX and STI, the Type RA Rear Bumper Ducts are a perfect combination of performance and style, offering improved airflow management for track or street applications.
