WRX STI owners, this genuine Subaru vortex generator isn't just for looks - it actually improves aerodynamics on your 2015-2019 sedan! The black plastic with painted finish matches your factory trim perfectly, and installation couldn't be simpler thanks to the peel-and-stick double-sided tape.

This OEM part gives you that peace of mind knowing it's designed specifically for your vehicle and won't interfere with anything. It helps manage airflow over your roof to reduce drag and improve stability at higher speeds. Just a heads up - it doesn't fit Starlink equipped vehicles, so double-check your specific model. Whether you're looking to enhance your car's performance or just want that aggressive factory-plus look, this vortex generator delivers both style and function. It's one of those mods that looks like it came from the factory but adds that extra edge that sets your WRX apart from the crowd.
