APR Performance Carbon Fiber Vortex Generator 2015-2021 WRX w/ 6.2 Inch Base Radio / 2015-2016 STI

APR Carbon Fiber Vortex Generator 15-21 Subaru WRX / STI | Pre-Preg Carbon Fiber | Aerodynamic Accessory

Overview

The APR Carbon Fiber Vortex Generator is a precision-engineered aerodynamic accessory designed specifically for 2015-2021 Subaru WRX and WRX STI models. Its primary function is to optimize airflow over the roof and rear window junction, an area prone to turbulent air separation due to the steep drop-off angle. By managing this airflow, the vortex generator reduces drag and enhances the performance of the rear wing, making it an ideal upgrade for enthusiasts seeking improved aerodynamic efficiency and stability at higher speeds.

Crafted from pre-preg carbon fiber, this vortex generator exemplifies APR’s commitment to lightweight, high-strength materials and meticulous manufacturing processes. The design philosophy centers on functional aerodynamics without compromising the vehicle’s OEM aesthetics. APR’s expertise in Subaru performance parts ensures this component integrates seamlessly with the WRX and STI’s roofline, maintaining a clean, OEM+ appearance while delivering measurable aerodynamic benefits.

For Subaru owners, this vortex generator translates into a more stable rear downforce profile, especially beneficial during spirited driving or track use. By delaying airflow separation and minimizing turbulence, it not only supports the rear wing’s effectiveness but also contributes to reduced drag, which can positively impact fuel efficiency and high-speed stability. Note that fitment requires the standard 6.2-inch Starlink radio; models equipped with the 7-inch Starlink headunit are not compatible.
