Using the APR Vortex Generator is easy. First, make sure the area on your Subaru WRX or STI where you'll install it is clean. Just stick it on following the provided instructions. When driving, you'll notice better performance thanks to reduced drag. As for maintenance, a simple wash with mild soap and water will keep it in good shape. Avoid using harsh chemicals as they might damage the carbon fiber. And be careful not to hit it against anything while cleaning or driving, as that could cause scratches or other damage.
