Product Description
Vortex generators benefit cars that have rear wings because it keeps the air flow hitting the top of the rear spoiler for optimal downforce. It helps the air flow make a smooth transition flowing from the roof and deflecting off the rear spoiler, rather than having the air crash in the low area between your windshield and rear spoiler.
Fitment:
Subaru WRX 2015-2021
Subaru STi 2015-2021
Warranty Disclaimer: Subaru of America will only warranty parts installed by a CERTIFIED Subaru Dealership. The part being installed must also match the vehicle VIN. IE If you install an STi block in a WRX at your friends shop, do not expect a warranty claim to come through if it explodes! Please use your best judgement.
