Subaru WRX / STI Carbon Fiber Vortex Generator (2017–2021)

APR Carbon Fiber Vortex Generators are engineered to optimize airflow on vehicles with steep roof-to-rear-window transitions, such as the Subaru WRX and STI. Without a vortex generator, airflow in this area becomes turbulent as it separates from the roofline, reducing rear wing effectiveness and increasing drag. The APR Vortex Generator delays separation, reduces turbulence, and improves rear wing efficiency—enhancing stability and aerodynamic performance at high speeds.

Features

• Pre-Preg Carbon Fiber Construction – Autoclave-cured for maximum strength and minimal weight.

• Improved Aerodynamics – Directs airflow for reduced turbulence, drag, and improved downforce.

• Vehicle-Specific Design – Engineered for Subaru WRX and STI fitment.

• Aggressive Styling – Carbon fiber finish provides a performance-inspired look.
